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

Optimize TransactionSynchronizationManager.getSynchronizations() to
avoid sorting and ArrayList creation in case of a single
TransactionSynchronization.

This commit adds support for Kotlin Coroutines to Spring AOP
by leveraging CoroutinesUtils#invokeSuspendingFunction in
AopUtils#invokeJoinpointUsingReflection to convert it to the
equivalent Publisher return value, like in other parts of Spring
Framework.
That allows method interceptors with Reactive support to process
related return values.
CglibAopProxy#processReturnType and JdkDynamicAopProxy#invoke
take care of the conversion from the Publisher return value
to Kotlin Coroutines.
Reactive transactional and HTTP service interface support
have been refined to leverage those new generic capabilities.

Includes ConfigurableTransactionManager interface for listener registration.
Includes additional introspection methods on TransactionExecution interface.
Includes default method declarations on TransactionStatus/SmartTransactionObject.
Closes gh-27479
TransactionalApplicationListener and TransactionalEventListener automatically detect a reactive TransactionContext as the event source and register the synchronization accordingly. TransactionalEventPublisher is a convenient delegate for publishing corresponding events with the current TransactionContext as event source. This can also serve as a guideline for similar reactive event purposes.
