The introduction of AdvisedSupport.AdvisorKeyEntry in Spring Framework
6.0.10 resulted in a regression regarding caching of CGLIB generated
proxy classes. Specifically, equality checks for the proxy class cache
became based partially on identity rather than equivalence. For
example, if an ApplicationContext was configured to create a
class-based @Transactional proxy, a second attempt to create the
ApplicationContext resulted in a duplicate proxy class for the same
@Transactional component.
On the JVM this went unnoticed; however, when running Spring
integration tests within a native image, if a test made use of
@DirtiesContext, a second attempt to create the test
ApplicationContext resulted in an exception stating, "CGLIB runtime
enhancement not supported on native image." This is because Test AOT
processing only refreshes a test ApplicationContext once, and the
duplicate CGLIB proxy classes are only requested in subsequent
refreshes of the same ApplicationContext which means that duplicate
proxy classes are not tracked during AOT processing and consequently
not included in a native image.
This commit addresses this regression as follows.
- AdvisedSupport.AdvisorKeyEntry is now based on the toString()
representations of the ClassFilter and MethodMatcher in the
corresponding Pointcut instead of the filter's and matcher's
identities.
- Due to the above changes to AdvisorKeyEntry, ClassFilter and
MethodMatcher implementations are now required to implement equals(),
hashCode(), AND toString().
- Consequently, the following now include proper equals(), hashCode(),
and toString() implementations.
- CacheOperationSourcePointcut
- TransactionAttributeSourcePointcut
- PerTargetInstantiationModelPointcut

Prior to this commit, `DisposableBeanAdapter` supported reactive bean
destroy methods by detected if `Publisher` is available on the
classpath. The AOT engine did not contribute a reflection hint for this
call.
This commit ensures that this reflection hint is registered in all
cases, even if there are no destroy methods detected on beans.
Fixes gh-31278
`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
This commit adds reflection hints for `jakarta.inject.Provider` and
ensures that hints are always contributed even if jakarta classes are
not on the classpath.
Fixes gh-31259
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
This commit reviews when an AOT-generated bean definition defines a
beanClass or targetType. Previously, a beanClass was not consistently
set which could lead to issues.
Closes gh-31242
Except for meaningful double spaces (for example, to align the
indentation of comments), this commit replaces all unnecessary double
spaces with single spaces in the spring-webmvc module.
Closes gh-31245
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
Prior to this commit in the message converters it was possible
to set a pre-configured ObjectMapper. However the constructor
would still create and configure an ObjectMapper.
With the added constructor it is now possible to directly
construct the message converter with the proper ObjectMapper.
This prevents the this additional ObjectMapper to be constructed.
