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.

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.

If a sub-class of Future (such as ListenableFuture) is used as a return
type and an exception is thrown, the AsyncUncaughtExceptionHandler is
called. Now checking for any Future implementation instead of a faulty
strict matching.
Issue: SPR-12797
This commit ensures that @NumberFormat can be used as a
meta-annotation, as was already the case for @DateTimeFormat.
In addition, this commit polishes FormattingConversionServiceTests and
MvcNamespaceTests.
Issue: SPR-12743
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.
Issue: SPR-12769
Reduce logging level when no target annotation is found a on bean. For
consistency, update ScheduledAnnotationBeanPostProcessor and
JmsListenerAnnotationBeanPostProcessor that define the same log
statement.
Issue: SPR-12574
If an `@EventListener` annotated method returns a Collection or an Array,
each individual items are now published as an event instead of publishing
one event with said collection.
Issue: SPR-12733
JmsInvokerClientInterceptor defines a receiveTimeout field but does not
handle such timeout. This commit adds an additional callback that throws
an RemoteTimeoutException instead.
Sub-classes can override the onReceiveTimeout to throw a different
exception or return a fallback RemoteInvocationResult.
Issue: SPR-12731
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.
Issue: SPR-12636
Previously, the exception-handler attribute was not taken care of when
task:annotation-driven is used in AspectJ mode. This commit provides the
expected behavior.
Issue: SPR-12619
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
Previously, one could only set the list of bean names to exclude from
auto-detection and there was no way to add additional bean names.
MBeanExporter now exposes a addExcludedBean method that can be invoked
during the initialization phase to add bean names to ignore.
Issue: SPR-12686
Move MethodCacheKey and related classes to the expression package so that
other parts of the framework can benefit ot it.
CacheExpressionEvaluator is a base class that can be used to cache SpEL
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.
Issue: SPR-12622
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.
Issue: SPR-12601
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.
Issue: SPR-12529
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.

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.

Update ConditionEvaluator to collect then sort Conditions before
evaluation. By annotating Conditions with @Ordered expensive operations

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).

Rework the @PropertySource parsing logic recently changed in commit
7c608886 to deal with the same source appearing on a @Configuration

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.
Issue: SPR-8045
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.
Issue: SPR-11955
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.
Issue: SPR-9705
Reorganized class structure to match our code style (setter for

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
