This commit provides an alternative
java.beans.Introspector#findCustomizerClass implementation
via a GraalVM substitution that avoids to include thousands
of unused AWT classes in the native image.
Closes gh-29060
This commit automatically registers runtime hints for
TestContextBootstrapper classes, including default bootstrappers as
well as any bootstrapper configured via @BootstrapWith.
Closes gh-29023
This commit introduces automatic registration of runtime hints for
ApplicationContextInitializers configured via the `initializers`
attribute in @ContextConfiguration.
See gh-29021
This commit moves the registration of runtime hints for ContextLoaders
from TestContextRuntimeHints to TestContextAotGenerator.
This allows for automatic registration of any ContextLoader used,
including custom loaders declared via the `loader` attribute in
@ContextConfiguration.

Since Spring no longer adds the SynthesizedAnnotation interface to the
JDK dynamic proxy used to synthesize an annotation, this commit
officially deprecates SynthesizedAnnotation and related methods in
RuntimeHintsUtils.
See gh-29041, gh-29054
Closes gh-29053
SynthesizedAnnotation was originally introduced as a convenience for
easily detecting if an annotation had been synthesized by Spring via a
simple `if (myAnnotation instanceof SynthesizedAnnotation)` check.
However, the introduction of SynthesizedAnnotation in the JDK dynamic
proxy for a synthesized annotation results in a separate proxy class
for each annotation synthesized by Spring, and this causes issues with
GraalVM native images since users and framework developers must always
ensure that the additional proxy classes are registered.
This commit completely removes the use of SynthesizedAnnotation in
synthesized annotation proxies. This change allows the proxy class for
an annotation to be reused for a synthesized annotation of the same
annotation type.
Consequently:
- Extra proxy classes are not generated on the JVM or in a native image.
- Extra proxy classes are not required to be registered for a native image.

This commit fixes Kotlin Serialization converter
registration logic in RestTemplate,
AbstractMessageBrokerConfiguration and
AllEncompassingFormHttpMessageConverter classes
to be similar to the one in
WebMvcConfigurationSupport.
Closes gh-29008
Add `MemberCategory` and `FieldMode` shortcuts for type registration.
Helper `builtWith` methods have also been extracted to the Hint types
to allow general reuse (for example with `registerTypes`).
See gh-29011
Add a `FieldMode` enum analogous to `ExecutableHint` and update
`FieldHint` to ensure that registration cannot downgrade `WRITE`
to `READ`.
Fixes gh-29055
Reduce the visibility of hint factory methods that return a `Builder`.
Since the `build()` method of the `Builder` is package-private the
factory methods can also be package-private.
Since SynthesizedAnnotation will be deprecated (and potentially
completely removed) in Spring Framework 6.0, this commit introduces
AnnotationUtils.isSynthesizedAnnotation(Annotation) in 5.3.x to allow
people to migrate away from relying on SynthesizedAnnotation.

Prior to this commit, the `ConcurrentLruCache` implementation would not
perform well under certain conditions. As long as the cache capacity was
not reached, the cache would avoid maintaining an eviction queue
(reordering entries depending with least/most recently read). When the
cache capacity was reached, the LRU queue was updated for each
read/write operation. This decreased performance significantly under
contention when the capacity was reached.
This commit completely rewrites the internals of `ConcurrentLruCache`.
`ConcurrentLruCache` is now a specialized version of the
`ConcurrentLinkedHashMap` [1]. This change focuses on buferring read and
write operations, only processing them at certain times to avoid
contention.
When a cached entry is read, a read operation is queued and buffered
operations are drained if the buffer reached a fixed limit. When a new
cache entry is added or removed, a write operation is queued and
triggers a drain attempt. When the capacity is outgrown, the cache polls
items from the eviction queue, which maintains elements with the
least recently used ones first. Entries are removed until the capacity
is under control.
The behavior described here and the buffer sizes are optimized with the
number of available processors in mind. Work is localized as much as
possible on a per-thread basis to avoid contention on the eviction queue.
The new implementation has been tested with the JMH benchmark provided
here, comparing the former `COncurrentLruCache`, the new implementation
as well as the `ConcurrentLinkedHashMap` [1].
When testing with a cache reaching capacity, under contention, with a
10% cache miss, we're seeing a 40x improvement compared to the previous
implementation and performance on par with the reference.
See [2] for how to replicate the benchmark.

The removal of the exclusion prevented spring-webmvc from being imported
into Eclipse IDE due to conflicting versions of dom4j on the classpath.

Prior to this commit, the `RuntimeHintsAgent` would instrument
`Method.invoke` in a way that fails when invoked methods are not public.
This commit ensures that before delegating the invocation call, the
instrumentation makes the method accessible before delegating the call.
Fixes gh-29046
This commit introduces TestContextRuntimeHints which is a
RuntimeHintsRegistrar implementation that makes core types and
annotations from the Spring TestContext Framework available at runtime
within a GraalVM native image.
TestContextRuntimeHints is registered automatically via the
"META-INF/spring/aot.factories" file in spring-test.
This commit also modifies TestContextAotGeneratorTests to assert the
expected runtime hints registered by TestContextRuntimeHints as well as
runtime hints for TestExecutionListener and ContextCustomizerFactory
implementations registered by SpringFactoriesLoaderRuntimeHints.
Closes gh-29028

This commit fixes a race condition in PartGenerator, used by
DefaultPartHttpMessageReader. The condition can occur when a
completion signal comes in, and the state is changed to IdleFileState
at the same time.
