This commit fixes a regression introduced by gh-21139
via the usage of Kotlin reflection to invoke HTTP
handler methods. It ensures that kotlin.Unit is treated
as void by returning null.
It also polishes CoroutinesUtils to have a consistent
handling compared to the regular case, and adds related
tests to prevent future regressions.
Closes gh-31648
In order to prevent leaks of large amounts of non-heap
memory (and potential other efficiency and performance side
effects), this commit updates ResourceUtils#useCachesIfNecessary
to leave the caching flag to its JVM default value for instances
of JarURLConnection.
The previous behavior was originally introduced via gh-9316 and
gh-13755 to avoid I/O failure during webapp hot reloading in
Servlet containers. This is not a popular deployment mode anymore
and we have not been able to reproduce the original issue with
a Java 17 JVM and Tomcat 10.
Closes gh-30955
Adding generated code in the default package is not supported as we
intend to import it, most probably from another package, and that is
not supported. While this situation is hard to replicate with Java,
Kotlin is unfortunately more lenient and users can end up in that
situation if they forget to add a package statement.
This commit checks for the presence of a valid package, and throws
a dedicated exception if necessary.
Closes gh-31628
This commit updates PathMatchingResourcePatternResolver to avoid
returning duplicate resources on MS Windows when searching using the
`classpath*:` prefix and a wildcard pattern that matches resources
which are directly present in a JAR as well as present via classpath
manifest entries.
Closes gh-31598
Allows Kotlin caller to get a non-nullable property,
using a default value when the property is not set.
A method already exists on PropertyResolver which does this,
but takes a Class parameter.
The extension method can eliminate the parameter via reified type,
similar to the other extension methods which exist already.
Closes gh-31523
Prior to this commit, the `ConcurrentReferenceHashMap#Segment` would
recalculate its element count during the restructure phase by
subtracting the number of polled elements from the queue to the current
count.
Later, the newly restructured `references` array would only contain
references that 1) are not in the set of elements to purge and
2) that hold a non-null value.
The issues with this approach are multiple. The newly calculated count
is only an estimate, as some situations can make it invalid, even
temporarily.
* since we initially collected all elements to be purged from the queue,
the GC might have collected new values. This means that we might
filter out more references that we initially intended to
* because the restructure operation re-creates new references for all
elements in the original array, we might later get references from the
queue that are not in the array anymore. This could lead to
"duplicate" removals for the same value
Because several methods in the Segment class have special no-op behavior
when `count == 0`, an invalid count can lead to keys appearing missing
when they are actually still present. In some scenarios, this can
decrease the performance of the cache since values need to be
recalculated.
This commit fixes this inconsistency count issue by first using an
estimate in order to decide whether the array needs a resize and then by
counting the actual numbers of elements inserted in the restructured
array as the new count.
Fixes gh-31373
Since the rewrite of ConcurrentLruCache in Spring Framework 6.0, an
attempt to create a ConcurrentLruCache with zero capacity results in an
IllegalArgumentException even though the documentation states that zero
capacity indicates "no caching, always generating a new value".
This commit restores the ability to configure a ConcurrentLruCache with
zero capacity and introduces corresponding tests (which were first
verified against the 5.3.x branch to ensure backward compatibility).
See gh-26320
Closes gh-31317
Given a @Configuration class named org.example.AppConfig which
contains @Bean methods, in Spring Framework 5.3.x and previous
versions, the following classes were created when generating the CGLIB
proxy.
org.example.AppConfig$$EnhancerBySpringCGLIB$$fd7e9baa
org.example.AppConfig$$FastClassBySpringCGLIB$$3fec86e
org.example.AppConfig$$EnhancerBySpringCGLIB$$fd7e9baa$$FastClassBySpringCGLIB$$82534900
Those class names indicate that 1 class was generated for the proxy for
the @Configuration class itself and that 2 additional FastClass
classes were generated to support proxying of @Bean methods in
superclasses.
However, since Spring Framework 6.0, the following classes are created
when generating the CGLIB proxy.
org.example.AppConfig$$SpringCGLIB$$0
org.example.AppConfig$$SpringCGLIB$$1
org.example.AppConfig$$SpringCGLIB$$2
The above class names make it appear that 3 proxy classes are generated
for each @Configuration class, which is misleading.
To address that and to align more closely with how such generated
classes were named in previous versions of the framework, this commit
modifies SpringNamingPolicy so that generated class names once again
include "FastClass" when the generated class is for a CGLIB FastClass
as opposed to the actual proxy for the @Configuration class.
Consequently, with this commit the following classes are created when
generating the CGLIB proxy.
org.example.AppConfig$$SpringCGLIB$$0
org.example.AppConfig$$SpringCGLIB$$FastClass$$0
org.example.AppConfig$$SpringCGLIB$$FastClass$$1

`PathMatchingResourcePatternResolver` is reflecting on
`org.eclipse.core.runtime.FileLocator` and invoking methods on it for
OSGi support. While this use case is highly unlikely in native images,
registering the reflection entry by itself should be enough.
Fixes gh-31271
This commit adds the relevant reflection hints required by
`KotlinDetector`; this class is trying to detect both `kotlin.Metadata`
and `kotlin.reflect.full.KClasses`.
Fixes gh- 31269
Prior to this commit, `ClassUtils#forName` would always attempt to
resolve the given class name as a nested type. For example, searching
for `org.example.Spring` would try to resolve:
* `org.example.Spring`
* if not available, try `org.example$Spring` as well
Java classes usually start with uppercase letters, so this additional
lookup can be costly and not very useful.
This commit only attempts nested class lookups when the previous segment
starts with an uppercase. So `org.example.Spring.Issue` will look for
`org.example.Spring$Issue`, but `org.example.Spring` will not.
Closes gh-31258
Prior to this commit, the `RuntimeHintsPredicates` would assume that
registering introspection or invocation hints for "all declared methods"
on a type would also include "all public methods". This is not true, as
the Java reflection API itself behaves differently.
`getDeclaredMethods()` does not return a superset of `getMethods()`, as
the latter can return inherited methods, but not the former.
Same reasoning applies to fields.
This commit fixes the hints predicates to only match if the correct hint
has been registered.
Fixes gh-31224
In light of the refinements to ObjectUtils, this commit updates
SynthesizedMergedAnnotationInvocationHandler to use
ObjectUtils.nullSafeHashCode() and removes the now obsolete code in
SynthesizedMergedAnnotationInvocationHandler.
See gh-29051
This commit reverts the deprecation of CommandLinePropertySource and
SimpleCommandLinePropertySource, since we have discovered that Spring
Boot actively uses SimpleCommandLinePropertySource in
org.springframework.boot.SpringApplication.
Closes gh-31207
This commit deprecates the various nullSafeHashCode methods taking array
types as they are superseded by Arrays.hashCode now. This means that
the now only remaining nullSafeHashCode method does not trigger a
warning only if the target type is not an array. At the same time, there
are multiple use of this method on several elements, handling the
accumulation of hash codes.
For that reason, this commit also introduces a nullSafeHash that takes
an array of elements. The only difference between Objects.hash is that
this method handles arrays.
The codebase has been reviewed to use any of those two methods when it
is possible.
Closes gh-29051
gh-30810 introduced explicit support for collections and maps in
ObjectUtils.nullSafeConciseToString() by invoking isEmpty() on a Map or
Collection to determine which concise string representation should be
used. However, this caused a regression in which an exception was
thrown if the Map or Collection was a proxy generated by
AbstractFactoryBean to support <util:set />, <util:list />, and
<util:map /> in XML configuration.
This commit addresses this set of regressions by always returning
"[...]" or "{...}" for a Collection or Map, respectively, disregarding
whether the map is empty or not.
Closes gh-31138
This commit revises the FilePatternResourceHintsRegistrar API and
introduces List<String> overrides of various var-args methods used with
the new builder API.

This commit refines Reactor field precomputing on native
to only compute at build-time fields in the reactor.core
package, since doing so in reactor.netty has unwanted side
effects like Epoll always disabled.
Closes gh-31141
Prior to this commit, `@Async` and `@EventListener` annotated methods
would lose the the logging and observation contexts whenever their
execution was scheduled on a different Thread.
The Context Propagation library supports this use case and can propagate
context values in ThreadLocals, Reactor Context and more.
This commit introduces a new `TaskDecorator` implementation that
leverages the Context Propagation library. When configured on a
`TaskExecutor`, this allows to properly propagate context value through
the execution of the task.
This implementation is completely optional and requires the
"io.micrometer:context-propagation" library on the classpath. Enabling
this feature must be done consciously and sometimes selectively, as
context propagation introduces some overhead.

If you wish to stop after a certain number of attempts with an
`ExponentialBackOff` you have to calculate the `maxElapsedTime`

Add a new property to make it more convenient to stop after a

Prior to this commit, when PathMatchingResourcePatternResolver
processed a `file:` pattern (for example, `file:/app-config/**`) for a
`rootPath` that did not exist in the filesystem, the resolver attempted
to search the directory and logged a WARNING message similar to the
following when it failed to do so.
Failed to search in directory [/app-config/] for files matching pattern
[**]: java.nio.file.NoSuchFileException: /app-config/
To avoid unnecessary attempts to search a nonexistent directory,
PathMatchingResourcePatternResolver now skips searching of a nonexistent
directory and preemptively logs an INFO message similar to the
following.
Skipping search for files matching pattern [**]: directory [/app-config]
does not exist
Closes gh-31111
This commit ensures that PathMatchingResourcePatternResolver's
doFindPathMatchingFileResources() method returns a mutable Set in order
to comply with the documented contract.
This commit implements StringToRegexConverter in Java
in order to avoid circular dependencies between Java
and Kotlin codes that can break IDE support, and for
consistency with the rest of the codebase.

This commit optimizes ClassUtils#getMostSpecificMethod which is
a method frequently invoked in typical Spring applications.
It refines ClassUtils#isOverridable by considering static and
final modifiers as non overridable and optimizes its implementation.
Closes gh-30272
Since an annotation cannot be extended in Java, there is no need to use
the INHERITED_ANNOTATIONS SearchStrategy to search for meta-annotations
on an annotation.
Prior to this commit, there was an issue with the semantics of property
source overrides. Specifically, a @PropertySource annotation present as
a meta-annotation on a @Configuration class was registered with higher
precedence than a @PropertySource annotation declared closer to (or
directly on) the @Configuration class. Consequently, there was no way
for a "local" @PropertySource annotation to override properties
registered via @PropertySource as a meta-annotation.
This commit addresses this issue by introducing a new overloaded
getMergedRepeatableAnnotationAttributes() variant in
AnnotatedTypeMetadata that allows the caller to supply a
sortByReversedMetaDistance flag. When set to `true`, the annotation
search results will be sorted in reversed order based on each
annotation's meta distance, which effectively orders meta-annotations
before annotations that are declared directly on the underlying element.
ConfigurationClassParser and AnnotationConfigUtils have been updated to
use this new repeatable annotation search method for @PropertySource.
Closes gh-31074
Reuses ValidationAnnotationUtils which is slightly optimized for the detection of Spring's Validated annotation now, also to the benefit of common web scenarios.

Includes query(Class) method with value and property mapping support on JdbcClient.
JdbcClient's singleColumn/singleValue are declared without a Class parameter now.
Closes gh-26594
See gh-30931
AnnotatedTypeMetadata has various methods for finding annotations;
however, prior to this commit it did not provide explicit support for
repeatable annotations.
Although it is possible to craft a search "query" for repeatable
annotations using the MergedAnnotations API via getAnnotations(), that
requires intimate knowledge of the MergedAnnotations API as well as the
structure of repeatable annotations.
Furthermore, the bugs reported in gh-30941 result from the fact that
AnnotationConfigUtils attempts to use the existing functionality in
AnnotatedTypeMetadata to find repeatable annotations without success.
This commit introduces a getMergedRepeatableAnnotationAttributes()
method in AnnotatedTypeMetadata that provides dedicated support for
finding merged repeatable annotation attributes with full @AliasFor
semantics.
Closes gh-31041
The Javadoc for getAnnotationAttributes() states that it supports
"attribute overrides on composed annotations"; however, it actually
supports @AliasFor in general, including attribute aliases within a
given annotation.
This commit updates the Javadoc and corresponding tests to reflect that.
Closes gh-31042
Java 12 introduced java.lang.Class#componentType() as a shortcut for
getComponentType().
Since we started using arrayType() in fe5560400c, this commit switches
to componentType() for consistent API usage style.
