Prior to this commit, dependency checks in the static initialization
block for MicrometerObservationRegistryTestExecutionListener resulted
in an ExceptionInInitializerError which led to verbose logging in
TestContextFailureHandler.
This commit improves the logging for missing dependencies in
MicrometerObservationRegistryTestExecutionListener by moving the
dependency checks to the constructor and by throwing a
NoClassDefFoundError instead of an IllegalStateException. This allows
TestContextFailureHandler to log a concise DEBUG message denoting that
the listener is being skipped due to missing dependencies.
This commit also now checks for the presence of
io.micrometer.context.ThreadLocalAccessor in addition to
io.micrometer.observation.contextpropagation.ObservationThreadLocalAccessor.
Furthermore, this commit now explicitly mentions the need for
io.micrometer:context-propagation in the error message.
The following demonstrate the generated DEBUB message when
ObservationThreadLocalAccessor and ThreadLocalAccessor are missing,
respectively.
Skipping candidate TestExecutionListener [org.springframework.test.context.observation.MicrometerObservationRegistryTestExecutionListener] due to a missing dependency. Specify custom TestExecutionListener classes or make the default TestExecutionListener classes and their required dependencies available. Offending class: io.micrometer.observation.contextpropagation.ObservationThreadLocalAccessor. MicrometerObservationRegistryTestExecutionListener requires io.micrometer:micrometer-observation:1.10.8 or higher and io.micrometer:context-propagation:1.0.3 or higher.

Prior to this commit, private (and non-visible package-private)
init/destroy methods were not supported in AOT mode. The reason is that
such methods are tracked using their fully-qualified method names, and
the AOT support for init/destroy methods previously did not take
fully-qualified method names into account. In addition, the invocation
order of init/destroy methods differed vastly between standard JVM mode
and AOT mode.
This commit addresses these issues in the following ways.
- AbstractAutowireCapableBeanFactory.invokeCustomInitMethod(),
DisposableBeanAdapter.determineDestroyMethod(), and
BeanDefinitionPropertiesCodeGenerator.addInitDestroyHint() now parse
fully-qualified method names to locate the correct init/destroy
methods.
- AbstractAutowireCapableBeanFactory and DisposableBeanAdapter delegate
to a new MethodDescriptor record which encapsulates the parsing of
fully-qualified method names; however,
BeanDefinitionPropertiesCodeGenerator duplicates this logic since it
resides in a different package, and we do not currently want to make
MethodDescriptor public.
- Init/destroy methods detected via annotations (such as @PostConstruct
and @PreDestroy) are now invoked prior to init/destroy methods that
are explicitly configured by name or convention. This aligns with the
invocation order in standard JVM mode; however,
InitializingBean#afterPropertiesSet() and DisposableBean#destroy()
are still invoked before annotated init/destroy methods in AOT mode
which differs from standard JVM mode.
- Unit and integration tests have been updated to test the revised
behavior.

This commits changes the return type from Publisher<?> to
Object in order to avoid potential compatibility issues when
the Reactive Streams dependency is not in the classpath.
Closes gh-30716
This commit updates AbstractMessageListenerContainer's Javadoc
regarding the log level used in invokeErrorHandler() so that the
documentation aligns with the implementation, namely that errors will
logged at WARN level if no ErrorHandler has been registered.
Closes gh-30730
This commit adds support for Kotlin parameter default values
in handler methods. It allows to write:
@RequestParam value: String = "default"
as an alternative to:
@RequestParam(defaultValue = "default") value: String
Both Spring MVC and WebFlux are supported, including on
suspending functions.

In the original implementation of
MicrometerObservationRegistryTestExecutionListener I accidentally
imported JUnit 5's org.junit.platform.launcher.TestExecutionListener
instead Spring's
org.springframework.test.context.TestExecutionListener. The code
therefore attempts to use the ClassLoader for the JUnit Platform's
TestExecutionListener which may fail to see the required types. In
addition, if the JUnit Platform's TestExecutionListener is not on the
classpath, the attempt to access its ClassLoader will fail.
This commit addresses this by properly using the ClassLoader for
Spring's TestExecutionListener to detect dependencies of the
MicrometerObservationRegistryTestExecutionListener.
Closes gh-30726
