for synchronized cache access (i.e. when the `sync` attribute on
`@Cacheable` is set to `true`).

This commit makes sure that the `unregister` order of registered
application contexts has no incidence on the removal of the LiveBeansView
MBean.
Rather than using the last application context's name to compute the
identity of the MBean to remove, the identity is stored when the MBean is
created.
This commit also adds missing tests.

Issue: SPR-14728
This commit adds a "spring-context-indexer" module that can be added to
any project in order to generate an index of candidate components defined
in the project.
`CandidateComponentsIndexer` is a standard annotation processor that
looks for source files with target annotations (typically `@Component`)
and references them in a `META-INF/spring.components` generated file.
Each entry in the index is the fully qualified name of a candidate
component and the comma-separated list of stereotypes that apply to that
candidate. A typical example of a stereotype is `@Component`. If a
project has a `com.example.FooService` annotated with `@Component` the
following `META-INF/spring.components` file is generated at compile time:
```
com.example.FooService=org.springframework.stereotype.Component
```
A new `@Indexed` annotation can be added on any annotation to instructs
the scanner to include a source file that contains that annotation. For
instance, `@Component` is meta-annotated with `@Indexed` now and adding
`@Indexed` to more annotation types will transparently improve the index
with additional information. This also works for interaces or parent
classes: adding `@Indexed` on a `Repository` base interface means that
the indexed can be queried for its implementation by using the fully
qualified name of the `Repository` interface.
The indexer also adds any class or interface that has a type-level
annotation from the `javax` package. This includes obviously JPA
(`@Entity` and related) but also CDI (`@Named`, `@ManagedBean`) and
servlet annotations (i.e. `@WebFilter`). These are meant to handle
cases where a component needs to identify candidates and use classpath
scanning currently.
If a `package-info.java` file exists, the package is registered using
a "package-info" stereotype.
Such files can later be reused by the `ApplicationContext` to avoid
using component scan. A global `CandidateComponentsIndex` can be easily
loaded from the current classpath using `CandidateComponentsIndexLoader`.
The core framework uses such infrastructure in two areas: to retrieve
the candidate `@Component`s and to build a default `PersistenceUnitInfo`.
Rather than scanning the classpath and using ASM to identify candidates,
the index is used if present.
As long as the include filters refer to an annotation that is directly
annotated with `@Indexed` or an assignable type that is directly
annotated with `@Indexed`, the index can be used since a dedicated entry
wil be present for that type. If any other unsupported include filter is
specified, we fallback on classpath scanning.
In case the index is incomplete or cannot be used, The
`spring.index.ignore` system property can be set to `true` or,
alternatively, in a "spring.properties" at the root of the classpath.
Issue: SPR-11890
Commit 240f254 has introduced support for `java.util.Optional` in the
cache abstraction. If such type is present, the contained value is cached
if it is present.
This new feature slightly changed the semantic of `#result` that was
documented up till this commit as the "return value of the method
invocation". This is no longer true as `#result` for `Optional<T>`
refers to the `T` instance and not the `Optional` instance.
This commit clarifies both the javadoc and the documentation.

Issue: SPR-14129
Prior to Java 8 it never really made much sense to author integration
tests using interfaces. Consequently, the Spring TestContext Framework
has never supported finding test-related annotations on interfaces in
its search algorithms.
However, Java 8's support for interface default methods introduces new
testing use cases for which it makes sense to declare test
configuration (e.g., @ContextConfiguration, etc.) on an interface
containing default methods instead of on an abstract base class.
This commit ensures that all non-repeatable, class-level test
annotations in the Spring TestContext Framework can now be declared on
test interfaces. The only test annotations that cannot be declared on
interfaces are therefore @Sql and @SqlGroup.
Issue: SPR-14184
It's handy to know in advance whether or not expression that is
passed to CronSequenceGenerator or CronTrigger constructor would
not results in IllegalArgumentException. The only way to do it
now is to try\catch an instance creation but it's kinda ugly.
This commit makes sure to reject an `@EventListener` annotated method
that also uses `@Async`. In such scenario, the method is invoked in a
separate thread and the infrastructure has no handle on the actual reply,
if any.
The documentation has been improved to refer to that scenario.

This commit reverts the recently added merged annotation support for
Spring's JMX annotations by once again using the simpler searches for
repeatable annotations in AnnotationUtils.
Issue: SPR-13973
Prior to this commit, @Cacheable, @CacheEvict, @CachePut, and @Caching
could be used to create custom stereotype annotations with hardcoded
values for their attributes; however, it was not possible to create
composed annotations with attribute overrides.
This commit addresses this issue by refactoring
SpringCacheAnnotationParser to use the newly introduced
findAllMergedAnnotations() method in AnnotatedElementUtils. As a
result, @Cacheable, @CacheEvict, @CachePut, and @Caching can now be
used to create custom composed annotations with attribute overrides
configured via @AliasFor.
Issue: SPR-13475
Previously, a package private `@ManagedResource` annotated bean was
registered to the JMX domain even if any attempt to invoke an operation
on it will fail since it has to be public.
This commit validates that any `@ManagedResource` annotated bean is
public and throws an InvalidMetadataException otherwise. Note that the
actual bean type does not have to be public as long as the class
annotated with `@ManagedResource` in the hierarchy is pubic and no extra
operations or attributes are defined on the child.

Previously, a ConfigurationClass created from AnnotationMetadata
and a ConfigurationClass created from a class would have subtly
different descriptions. Given a class named com.example.Foo, the
former’s description would be “com.example.Foo”, whereas the latter’s

This commit updates ConfigurationClass to make the description
consistent, preferring the description without “class” in it.

This change updates all cases where callbacks are invoked to catch and

ListenableFuture not the callbacks themselves.
Issue: SPR-13785
ConcurrentMapCacheManager and ConcurrentMapCache now support the
serialization of cache entries via a new `storeByValue` attribute. If it is
explicitly enabled, the cache value is first serialized and that content
is stored in the cache.
The net result is that any further change made on the object returned
from the annotated method is not applied on the copy held in the cache.
Issue: SPR-13758
Previously, if a `@Cacheable` method was accessed with the same key by
multiple threads, the underlying method was invoked several times instead
of blocking the threads while the value is computed. This scenario
typically affects users that enable caching to avoid calling a costly
method too often. When said method can be invoked by an arbitrary number
of clients on startup, caching has close to no effect.
This commit adds a new method on `Cache` that implements the read-through
pattern:
```
<T> T get(Object key, Callable<T> valueLoader);
```
If an entry for a given key is not found, the specified `Callable` is
invoked to "load" the value and cache it before returning it to the
caller. Because the entire operation is managed by the underlying cache
provider, it is much more easier to guarantee that the loader (e.g. the
annotated method) will be called only once in case of concurrent access.
A new `sync` attribute to the `@Cacheable` annotation has been addded.
When this flag is enabled, the caching abstraction invokes the new
`Cache` method define above. This new mode bring a set of limitations:
* It can't be combined with other cache operations
* Only one `@Cacheable` operation can be specified
* Only one cache is allowed
* `condition` and `unless` attribute are not supported
The rationale behind those limitations is that the underlying Cache is
taking care of the actual caching operation so we can't really apply
any SpEL or multiple caches handling there.
Issue: SPR-9254
Previously, if a managed bean had only one non-default constructor, we
should still annotate it with `@Autowired` to properly use constructor
injection. Not doing so resulted in an error as the container was
trying to call the default (non-existing) constructor.
This commit updates this behaviour to automatically applyed the
autowiring semantic to any bean that has only one constructor. As
before, if more than one constructor is defined, `@Autowired` must be
specified to teach the container the constructor it has to use.

Even though the JSR-107 spec forbids to store null values, our cache
abstraction allows that behaviour with a special handled (and this is
the default behaviour).
While this was working fine with our own set of annotations, the
JSR-107 interceptor counterpart was interpreting the spec sensu strictu.
We now allow for that special case as well.

SPR-11512 introduced support for annotation attribute aliases via
@AliasFor, requiring the explicit declaration of the 'attribute'
attribute. However, for aliases within an annotation, this explicit
declaration is unnecessary.
This commit improves the readability of alias pairs declared within an
annotation by introducing a 'value' attribute in @AliasFor that is an
alias for the existing 'attribute' attribute. This allows annotations
such as @ContextConfiguration from the spring-test module to declare
aliases as follows.
public @interface ContextConfiguration {
@AliasFor("locations")
String[] value() default {};
@AliasFor("value")
String[] locations() default {};
// ...
}
Issue: SPR-13289
In addition to specifying the event type to listen to via a method
parameter, any @EventListener annotated method can now alternatively
define the event type(s) to listen to via the "classes" attributes (that
is aliased to "value").
Something like
@EventListener({FooEvent.class, BarEvent.class})
public void handleFooBar() { .... }
Issue: SPR-13156
Prior to this commit, the implementation of getRepeatableAnnotation()
in Spring's AnnotationUtils complied neither with the contract of
getAnnotationsByType() nor with the contract of
getDeclaredAnnotationsByType() as defined in AnnotatedElement in Java 8.
Specifically, unexpected results can be encountered when using Spring's
support for @Repeatable annotations: either annotations show up in the
returned set in the wrong order, or annotations are returned in the set
that should not even be found based on the semantics of @Repeatable.
This commit remedies this problem by deprecating the existing
getRepeatableAnnotation() methods and replacing them with new
getRepeatableAnnotations() and getDeclaredRepeatableAnnotations()
methods that comply with the contracts of Java's getAnnotationsByType()
and getDeclaredAnnotationsByType(), respectively.
Issue: SPR-13068
In AnnotatedElementUtils, all methods pertaining to merging annotation
attributes have been renamed to "getMerged*()" and "findMerged*()"
accordingly. Existing methods such as getAnnotationAttributes(..) have
been deprecated in favor of the more descriptive "merged" variants.
This aligns the naming conventions in AnnotatedElementUtils with those
already present in AnnotationReadingVisitorUtils.
The use of "annotationType" as a variable name for the fully qualified
class name of an annotation type has been replaced with
"annotationName" in order to improve the readability and intent of the
code base.
In MetaAnnotationUtils.AnnotationDescriptor, getMergedAnnotation() has
been renamed to synthesizeAnnotation(), and the method is now
overridden in UntypedAnnotationDescriptor to always throw an
UnsupportedOperationException in order to avoid potential run-time
ClassCastExceptions.
Issue: SPR-11511
Provide a mean to detect the actual ResolvableType based on a instance as
a counter measure to type erasure.
Upgrade the event infrastructure to detect if the event (or the payload)

method signature of the listener.
Issue: SPR-13069
While working on SPR-12532, an extra IdentityWrapper was added to work
around a backward compatible issue between commons pool 1.x and 2.x. This
issue (POOL-283) has actually been fixed in 2.4 and their IdentityWrapper
is using object equality so our wrapper is in the way.
Looking retrospectively, the code looks all fine without the workaround
and commons pool 2.4 or later so it has been removed.
Since Spring 4.1, a CacheResolver may be configured to customize the way
the cache(s) to use for a given cache operation are retrieved. Since a
CacheResolver implementation may not use the cache names information at
all, this attribute has been made optional.
However, a fix was still applied, preventing a Cache operation without a
cache name to be defined properly. We now allow this valid use case.
Issue: SPR-13081
This commit introduces new 'cacheNames' attributes (analogous to the
existing attribute of the same name in @CacheConfig) as aliases for the
'value' attributes in @Cacheable, @CachePut, and @CacheEvict.
In addition, SpringCacheAnnotationParser.getAnnotations() has been
refactored to support synthesized annotations.
Issue: SPR-11393
Prior to this commit, @ComponentScan already had a value/basePackages
alias pair; however, the semantics were not properly enforced.
This commit addresses this issue by refactoring
ComponentScanAnnotationParser to ensure that it is not possible to
declare both of the aliased attributes. In addition, the 'value' and
'basePackages' attributes are now annotated with @AliasFor in order to
make the semantics clearer.
Issue: SPR-11393
Spring Framework 4.2 RC1 introduced support for synthesizing an
annotation from an existing annotation in order to provide additional
functionality above and beyond that provided by Java. Specifically,
such synthesized annotations provide support for @AliasFor semantics.
As luck would have it, the same principle can be used to synthesize an
annotation from any map of attributes, and in particular, from an
instance of AnnotationAttributes.
The following highlight the major changes in this commit toward
achieving this goal.
- Introduced AnnotationAttributeExtractor abstraction and refactored
SynthesizedAnnotationInvocationHandler to delegate to an
AnnotationAttributeExtractor.
- Extracted code from SynthesizedAnnotationInvocationHandler into new
AbstractAliasAwareAnnotationAttributeExtractor and
DefaultAnnotationAttributeExtractor implementation classes.
- Introduced MapAnnotationAttributeExtractor for synthesizing an
annotation that is backed by a map or AnnotationAttributes instance.
- Introduced a variant of synthesizeAnnotation() in AnnotationUtils
that accepts a map.
- Introduced findAnnotation(*) methods in AnnotatedElementUtils that
synthesize merged AnnotationAttributes back into an annotation of the
target type.
The following classes have been refactored to use the new support for
synthesizing AnnotationAttributes back into an annotation.
- ApplicationListenerMethodAdapter
- TestAnnotationUtils
- AbstractTestContextBootstrapper
- ActiveProfilesUtils
- ContextLoaderUtils
- DefaultActiveProfilesResolver
- DirtiesContextTestExecutionListener
- TestPropertySourceAttributes
- TestPropertySourceUtils
- TransactionalTestExecutionListener
- MetaAnnotationUtils
- MvcUriComponentsBuilder
- RequestMappingHandlerMapping
In addition, this commit also includes changes to ensure that arrays
returned by synthesized annotations are properly cloned first.
Issue: SPR-13067
This commit introduces first-class support for aliases for annotation
attributes. Specifically, this commit introduces a new @AliasFor
annotation that can be used to declare a pair of aliased attributes
within a single annotation or an alias from an attribute in a custom
composed annotation to an attribute in a meta-annotation.
To support @AliasFor within annotation instances, AnnotationUtils has
been overhauled to "synthesize" any annotations returned by "get" and
"find" searches. A SynthesizedAnnotation is an annotation that is
wrapped in a JDK dynamic proxy which provides run-time support for
@AliasFor semantics. SynthesizedAnnotationInvocationHandler is the
actual handler behind the proxy.
In addition, the contract for @AliasFor is fully validated, and an
AnnotationConfigurationException is thrown in case invalid
configuration is detected.
For example, @ContextConfiguration from the spring-test module is now
declared as follows:
public @interface ContextConfiguration {
@AliasFor(attribute = "locations")
String[] value() default {};
@AliasFor(attribute = "value")
String[] locations() default {};
// ...
}
The following annotations and their related support classes have been
modified to use @AliasFor.
- @ManagedResource
- @ContextConfiguration
- @ActiveProfiles
- @TestExecutionListeners
- @TestPropertySource
- @Sql
- @ControllerAdvice
- @RequestMapping
Similarly, support for AnnotationAttributes has been reworked to
support @AliasFor as well. This allows for fine-grained control over
exactly which attributes are overridden within an annotation hierarchy.
In fact, it is now possible to declare an alias for the 'value'
attribute of a meta-annotation.
For example, given the revised declaration of @ContextConfiguration
above, one can now develop a composed annotation with a custom
attribute override as follows.
@ContextConfiguration
public @interface MyTestConfig {
@AliasFor(
annotation = ContextConfiguration.class,
attribute = "locations"
)
String[] xmlFiles();
// ...
}
Consequently, the following are functionally equivalent.
- @MyTestConfig(xmlFiles = "test.xml")
- @ContextConfiguration("test.xml")
- @ContextConfiguration(locations = "test.xml").
Issue: SPR-11512, SPR-11513
Previously, a Bean implementing `AutoCloseable` (or `Closeable`) was
always destroyed regardless of its bean definition. In particular, the
documented way of disabling the destruction callback via an empty String
did not work.
AutoCloseable beans are now treated pretty much as any other bean: we
still use the presence of the interface to optimize the check of a
destroy method and we only auto-discover the method name to invoke if
the inferred mode is enabled.
Issue: SPR-13022
In general, the Spring Framework aims to construct error message
strings only if an actual error has occurred. This seems to be the
common pattern in the codebase and saves both CPU and memory. However,
there are some places where eager error message formatting occurs
unnecessarily.
This commit addresses this issue in the following classes:
AdviceModeImportSelector, AnnotationAttributes, and
ReadOnlySystemAttributesMap.
The change in ReadOnlySystemAttributesMap also avoids a potential
NullPointerException.

This commit introduces support for finding annotations on abstract,
bridge, and interface methods in AnnotatedElementUtils.
- Introduced dedicated findAnnotationAttributes() methods in
AnnotatedElementUtils that provide first-class support for
processing methods, class hierarchies, interfaces, bridge methods,
etc.
- Introduced find/get search algorithm dichotomy in
AnnotatedElementUtils which is visible in the public API as well as
in the internal implementation. This was necessary in order to
maintain backwards compatibility with the existing API (even though
it was undocumented).
- Reverted all recent changes made to the "get semantics" search
algorithm in AnnotatedElementUtils in order to ensure backwards
compatibility, and reverted recent changes to
JtaTransactionAnnotationParser and SpringTransactionAnnotationParser
accordingly.
- Documented internal AnnotatedElementUtils.Processor<T> interface.
- Enabled failing tests and introduced
findAnnotationAttributesFromBridgeMethod() test in
AnnotatedElementUtilsTests.
- Refactored ApplicationListenerMethodAdapter.getCondition() and
enabled failing test in TransactionalEventListenerTests.
- AnnotationUtils.isInterfaceWithAnnotatedMethods() is now package
private.

Previously, a cache infrastructure with only a CacheResolver would have
worked fine until the JSR-107 API is added to the classpath. When this is
the case, the JCache support kicks in and an exception cache resolver is
all of the sudden required.
The CacheResolver _is_ different as the default implementation does look
different attributes so if a custom CacheResolver is set, it is not
possible to "reuse" it as a fallback exception CacheResolver.
Now, an exception CacheResolver is only required if a JSR-107 annotation
with an "exceptionCacheName" attribute is processed (i.e. the exception
CacheResolver is lazily instantiated if necessary).
The use case of having a CachingConfigurerSupport with only a
CacheResolver was still broken though since the JCache support only looks
for a JCacheConfigurer bean (per the generic type set on
AbstractCachingConfiguration). This has been fixed as well.

Previously, adding `@EnableAsync` on a blank application would lead to an
info message stating that `ProxyAsyncConfiguration` is not eligible for
getting processed by all BeanPostProcessors. Concretely, this is ok as
such internal configuration is not meant to be a target of such post
processing.
Revisit the condition for non infrastructure bean only. Add the
infrastructure role to a set of internal configuration, including the
`ProxyAsyncConfiguration`.
Issue: SPR-12761
Prior to this commit, the GroovyBeanDefinitionReader claimed (via its
Javadoc) that it fully supported XML configuration files in addition to
its Groovy DSL; however, this was unfortunately inaccurate since XML
validation was disabled by default which led to certain features of XML
configuration not working. For example, it was impossible to define a
<qualifier> in an XML config file without specifying the 'type'
attribute (which has a default value defined in the spring-beans XSD).
This commit fixes this issue by ensuring that bean definitions in XML
resources are loaded with a "standard" XmlBeanDefinitionReader that is
created with default settings (i.e., with XML validation enabled). With
regard to backwards compatibility, bean definitions defined using the
Groovy DSL are still loaded with an XmlBeanDefinitionReader that has
XML validation disabled by default which is necessary for proper
parsing of the Groovy DSL.

Deprecated CommonsPoolTargetSource (supporting commons pool 1.5+) in
favor of CommonsPool2TargetSource with a similar contract.
Commons Pool 2.x uses object equality while Commons Pool 1.x used
identity equality. This clearly means that Commons Pool 2 behaves
differently if several instances having the same identity according to
their `Object#equals(Object)` method are managed in the same pool. To
provide a smooth upgrade, a backward-compatible pool is created by
default; use `setUseObjectEquality(boolean)` if you need the standard
Commons Pool 2.x behavior.
Issue: SPR-12532
Previously, the `@Order` annotation was managed in an inconsistent way
when placed at the implementation level. For simple beans, it was
discovered properly but wasn't for beans requiring a proxy.
OrderComparator.SourceProvider now explicitly allows to return several
order sources; the default implementation returns not only the factory
method (if any) but also the target class if it happens to be different
from the class of the bean.

Update the application event listener infrastructure to support events
that are processed according to a transactional phase.
Introduce EventListenerFactory that can be implemented to provide support
for additional event listener types. TransactionalEventListener is a new
annotation that can be used in lieu of the regular EventListener. Its
related factory implementation is registered in the context automatically
via @EnableTransactionManagement or <tx:annotation-driven/>
By default, a TransactionalEventListener is invoked when the transaction
has completed successfully (i.e. AFTER_COMMIT). Additional phases are
provided to handle BEFORE_COMMIT and AFTER_ROLLBACK events.
If no transaction is running, such listener is not invoked at all unless
the `fallbackExecution` flag has been explicitly set.
Issue: SPR-12080
Add support for annotation-based event listeners. Enabled automatically
when using Java configuration or can be enabled explicitly via the
regular <context:annotation-driven/> XML element. Detect methods of
managed beans annotated with @EventListener, either directly or through
a meta-annotation.
Annotated methods must define the event type they listen to as a single
parameter argument. Events are automatically filtered out according to
the method signature. When additional runtime filtering is required, one
can specify the `condition` attribute of the annotation that defines a
SpEL expression that should match to actually invoke the method for a
particular event. The root context exposes the actual `event`
(`#root.event`) and method arguments (`#root.args`). Individual method
arguments are also exposed via either the `a` or `p` alias (`#a0` refers
to the first method argument). Finally, methods arguments are exposed via
their names if that information can be discovered.
Events can be either an ApplicationEvent or any arbitrary payload. Such
payload is wrapped automatically in a PayloadApplicationEvent and managed
explicitly internally. As a result, users can now publish and listen
for arbitrary objects.
If an annotated method has a return value, an non null result is actually
published as a new event, something like:
@EventListener
public FooEvent handle(BarEvent event) { ... }
Events can be handled in an aynchronous manner by adding `@Async` to the
event method declaration and enabling such infrastructure. Events can
also be ordered by adding an `@Order` annotation to the event method.
Issue: SPR-11622
Update the event publishing infrastructure to support generics-based
events, that is support ApplicationListener implementations that define
a generic event, something like:
public class MyListener
implements ApplicationListener<GenericEvent<String>> { ... }
This listener should only receive events that are matching the generic
signature, for instance:
public class StringEvent extends GenericEvent<String> { ... }
Note that because of type erasure, publishing an event that defines the
generic type at the instance level will not work. In other words,
publishing "new GenericEvent<String>" will not work as expected as type
erasure will define it as GenericEvent<?>.
To support this feature, use the new GenericApplicationListener that
supersedes SmartApplicationListener to handle generics-based even types via
`supportsEventType` that takes a ResolvableType instance instead of the
simple Class of the event. ApplicationEventMulticaster has an additional
method to multicast an event based on the event and its ResolvableType.
Issue: SPR-8201

expressions based on its annotation source (i.e. method). Sub-classing
that base class provides a simple to use API to retrieve Expression
instances efficiently.

This commit overhauls several of the tests that interact with an
MBeanServer with the goal of increasing the reliability of these tests.
- MBeanClientInterceptorTests now uses JUnit "assumptions" instead of
preemptively returning from test methods, thus allowing such methods
to be properly marked as "ignored" instead of "passed".
- MBeanClientInterceptorTests now uses JUnit's support for expected
exceptions where appropriate.
- MBeanClientInterceptorTests and RemoteMBeanClientInterceptorTests now
use Spring's SocketUtils to find an available TCP port when starting
an MBeanServer instead of aborting the tests when the default JMX
port is not available.

Commit 65d163e changed the textual message of an exception thrown by
ScheduledAnnotationBeanPostProcessor.afterSingletonsInstantiated(), and
this in turn caused the withAmbiguousTaskSchedulers_andSingleTask()
method in EnableSchedulingTests to start failing (albeit only during
'Performance' builds).
This commit updates the assertion to match the current implementation of
ScheduledAnnotationBeanPostProcessor.
Previously, if a bean has a scoped proxy and is annotated to be exposed
to the JMX domain, both the scoped proxy and the target instance were
exposed in the JMX domain, resulting in a duplicate entries. Worse, if
such bean defines an explicit name, the application wouldn't start
because of a name conflict.
This commit deals explicitely with scoped proxy and make sure to only
expose the relevant bean.

Only compute the error message to display when the generated key is
actually null instead of using Assert.notNull as the cache operation
'toString()' method is non trivial and gets computed regardless of the
result.
Issue: SPR-12527
Previously, any @Configuration class was enhanced to namely implement
DisposableBean in order to remove static callbacks that were registered
for that class. This leads to problem if an ApplicationContext is created
and destroyed within the lifecycle on another ApplicationContext in the
same class loader.
It turns out that the destruction callback is no longer necessary as the
interceptors are now stateless: the VM is free to reclaim any of those if
necessary.

The removed test testConfigFileParsingErrorWhenNamedBeans() could cause
a groovyc compilation error, for example when using latest IntelliJ IDEA.

ScheduledAnnotationBeanPostProcessor uses getBean(Class) for TaskScheduler/ScheduledExecutorService retrieval, allowing for a scheduler bean to be flagged as primary, and for a TaskScheduler bean to override a ScheduledExecutorService bean.
ContextLifecycleScheduledTaskRegistrar hooks into SmartInitializingSingleton's afterSingletonsInstantiated callback instead of ContextRefreshedEvent, as a natural consequence of SmartInitializingSingleton's introduction in Spring Framework 4.1 GA.
Prior to this commmit, any configuration class holding a CacheManager
bean would be eagerly instantiated. This is because the
CacheConfiguration infrastructure requests all beans of type
CacheManager.
This commit defers the resolution of the CacheManager as late
as possible.

Refine the logic introduced in commit 71c6eb2b so that additional
imported @Configuration classes are not considered as candidates if
they have already been parsed.

Refine property source ordering so that sources already contained in the
environment remain before those added by @PropertySource annotations.

Update JndiLocatorDelegate.isDefaultJndiEnvironmentAvailable() to
call `getEnvironment()` on the `InitialContext` in order to actually
trigger a NamingException if JNDI is not available.
Issue: SPR-12223
Update ConditionEvaluator to collect then sort Conditions before
evaluation. By annotating Conditions with @Ordered expensive operations
can be pushed to the back of the queue.
Issue: SPR-12219
Update ImportRegistry to track all import registrations that occur
against an importing class (rather than just keeping the last). In
addition, prune imported classes from the registry when a configuration
class is removed during the REGISTER_BEAN ConfigurationPhase.
This update prevents incorrect metadata from being injected into an
ImportAware class which is imported twice by different configurations
classes (when one of the configuration classes will be ultimately skipped
due to a @Condition).
Issue: SPR-12128
Rework the @PropertySource parsing logic recently changed in commit
7c608886 to deal with the same source appearing on a @Configuration
class and an @Import class.
Processing now occurs in a single sweep, with any previously added
sources being converted to a CompositePropertySource.
Issue: SPR-12115
Other PropertySources and in particular @ComponentScan can benefit from previously declared property sources on the same configuration class.

Prior to this commit, only @Async annotated methods with proxy style
had their custom uncaught exception handler applied. This commit
harmonizes the configuration so that AspectJ applies that behaviour as
well.

This commit adds the missing 4.1 XSDs for the following components:
* spring-aop
* spring-context
* spring-jee
* spring-lang
* spring-tx
* spring-util
These are strictly identical to the definition of the 4.0 XSDs.

This commit removes the immediate package dependency cycle between the context and jmx packages. A specific callback arrangement will follow in time for 4.1 RC1; at this point, it's temporarily back to registration kicked off by afterPropertiesSet again.

Commit eea230f introduced a regression by adding a support for the
"result" variable in SpEL expression for @CachePut. As such expressions
cannot be evaluated upfront anymore, any method that contains both
@Cacheable and @CachePut annotations are always executed even when
their conditions are mutually exclusive.
This is an example of such mutual exclusion
@Cacheable(condition = "#p1", key = "#p0")
@CachePut(condition = "!#p1", key = "#p0")
public Object getFooById(Object id, boolean flag) { ... }
This commit updates CacheEvaluationContext to define a set of
unavailable variables. When such variable is accessed for a given
expression, an exception is thrown. This is used to restore the
evaluation of the @CachePut condition upfront by registering "result"
as an unavailable variable.
If all @CachePut operations have been excluded by this upfront check,
the @Cacheable operation is processed as it was before. Such upfront
check restore the behavior prior to eea230f.

GroovyBeanDefinitionReader and Groovy ApplicationContexts redirect ".xml" files to XmlBeanDefinitionReader now, similar to what they've been doing for importBeans directives already. Analogously, @ImportResource for configuration classes redirects ".groovy" to GroovyBeanDefinitionReader now.

This commit validates that the changes introduced in 8221c9abc5 are
indeed allowing DirectFieldBindingResult to support nested validation
paths.
Issue: SPR-10623
This commit adds a nested path support for DirectFieldAccessor that is
similar to what BeanWrapper provides. It is now possible to use
expressions such as "person.address.city.name" to access the name of
the city that a given person lives in using fields to traverse the
graph.
DirectFieldAccessor also now supports an auto-grow option to create
a default instance for a "null" intermediate path. This option is
false by default and leads to a NullValueInNestedPathException in such
a case.
This commit also harmonizes part of the tests suite so that core tests
are shared between BeanWrapperImpl and DirectFieldAccessor.
Note that map and list access is not implemented as part of this
commit.

Reorganized class structure to match our code style (setter for
properties at the top of the class, public method before private
implementation).
Removed DisposableBean as it the lifecycle is already taking care
of removing MBeans on stop.
Cleaned test suite

Prior to this commit, MBeans were registered in a post construct
call of MBeanExporter. This commit moves that logic after the
initialization phase using the SmartLifecycle callback.

This commit introduces OrderProvider and OrderProviderComparator, two
interfaces designed to externalize how a collection of element is sorted
according to their order value.
FactoryAwareOrderProvider is an OrderProvider implementation that knows
about the objects to order and the corresponding BeanFactory instance.
This allows to retrieve additional metadata about the actual instances
to sort, such as its factory method.
A @Bean method can now holds an additional @Order to define the order
value that this bean should have when injected as part of a collection
or array.
Issue: SPR-11310
This commit adds a invokeOperation protected method in case one
needs a hook point in the way the underlying cache method is invoked,
and how exceptions that might be thrown by that invocation are handled.

Prior to this commit, CacheResolver could not be configured through
the XML namespace (i.e. cache:annotation-driven). This is now the
case.
Issue: SPR-11490
This commit adds the necessary infrastructure to handle exceptions
thrown by a cache provider in both Spring's and JCache's caching
abstractions.
Both interceptors can be configured with a CacheErrorHandler that
defines several callbacks on typical cache operations. In particular,
handleCacheGetError can be implemented in such a way that an
exception thrown by the provider is handled as a cache miss by the
caching abstraction.
The handler can be configured with both CachingConfigurer and the
XML namespace (error-handler property)

Animal sniffer provides tools to assist verifying that classes
compiled with a newer JDK are compatible with an older JDK.
This integratesthe latest version of the tool (1.11) that
permits the use of custom annotations. Added @UsesJava7,
@UsesJava8 and @UsesSunHttpServer and annotated the few places
where we rely on a specific environment.
The verification process can be invoked by running the 'sniff'
task.

This commits fixes a confusing phrasing of Cacheable javadoc that
mentioned explicitly that the method signature is used to compute the

This commit adds the support of JMS annotated endpoint. Can be
activated both by @EnableJms or <jms:annotation-driven/> and
detects methods of managed beans annotated with @JmsListener,
either directly or through a meta-annotation.
Containers are created and managed under the cover by a registry
at application startup time. Container creation is delegated to a
JmsListenerContainerFactory that is identified by the containerFactory
attribute of the JmsListener annotation. Containers can be
retrieved from the registry using a custom id that can be specified
directly on the annotation.
A "factory-id" attribute is available on the container element of
the XML namespace. When it is present, the configuration defined at
the namespace level is used to build a JmsListenerContainerFactory
that is exposed with the value of the "factory-id" attribute. This can
be used as a smooth migration path for users having listener containers
defined at the namespace level. It is also possible to migrate all
listeners to annotated endpoints and yet keep the
<jms:listener-container> or <jms:jca-listener-container> element to
share the container configuration.
The configuration can be fine-tuned by implementing the
JmsListenerConfigurer interface which gives access to the registrar
used to register endpoints. This includes a programmatic registration
of endpoints in complement to the declarative approach. A default
JmsListenerContainerFactory can also be specified to be used if no
containerFactory has been set on the annotation.
Annotated methods can have flexible method arguments that are similar
to what @MessageMapping provides. In particular, jms listener endpoint
methods can fully use the messaging abstraction, including convenient
header accessors. It is also possible to inject the raw
javax.jms.Message and the Session for more advanced use cases. The
payload can be injected as long as the conversion service is able to
convert it from the original type of the JMS payload. By
default, a DefaultJmsHandlerMethodFactory is used but it can be
configured further to support additional method arguments or to
customize conversion and validation support.
The return type of an annotated method can also be an instance of
Spring's Message abstraction. Instead of just converting the payload,
such response type allows to communicate standard and custom headers.
The JmsHeaderMapper infrastructure from Spring integration has also
been migrated to the Spring framework. SimpleJmsHeaderMapper is based
on SI's DefaultJmsHeaderMapper. The simple implementation maps all
JMS headers so that the generated Message abstraction has all the
information stored in the protocol specific message.
