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.

Prior to this commit, if an init/destroy method was package-private and
declared in a superclass in a package different from the package in
which the registered bean resided, a local init/destroy method with the
same name would effectively "shadow" the method from the different
package, resulting in only the local init/destroy method being invoked.
This commit addresses this issue by tracking package-private init
methods from different packages using their fully-qualified method
names, analogous to the existing support for private init/destroy
methods.

Previously, a bean definition that is optimized AOT could have
different metadata based on whether its resolved type had a generic or
not. This is due to RootBeanDefinition taking either a Class or a
ResolvableType doing fundamentally different things. While the former
sets the bean class which is to little use with an instance supplier,
the latter specifies the target type of the bean.
This commit sets the target type of the bean, using the existing
setter methods that take either a class or a ResolvableType and set the
same attribute consistently.

This commit enhances the `ScheduledAnnotationBeanPostProcessor` to
instrument `@Scheduled` methods declared on beans. This will create
`"tasks.scheduled.execution"` observations for each execution of a
scheduled method. This supports both blocking and reactive variants.
By default, observations are no-ops; developers must configure the
current `ObservationRegistry` on the `ScheduledTaskRegistrar` by using a
`SchedulingConfigurer`.
Closes gh-29883
This allows re-use of existing MethodParameter instances from controller
methods with cached metadata, and also ensures additional capabilities
such as looking up parameter annotations on interfaces.
See gh-29825
This commit makes sure that profiles that have been explicitly enabled
during AOT optimizations are automatically enabled when using those
optimizations.
If other profiles are set at runtime, they take precedence over the ones
defined during AOT processing.

This commit adds support for `@Scheduled` annotation on reactive
methods and Kotlin suspending functions.
Reactive methods are methods that return a `Publisher` or a subclass
of `Publisher`. The `ReactiveAdapterRegistry` is used to support many
implementations, such as `Flux`, `Mono`, `Flow`, `Single`, etc.
Methods should not take any argument and published values will be
ignored, as they are already with synchronous support.
This is implemented in `ScheduledAnnotationReactiveSupport`, which
"converts" Publishers to `Runnable`. This strategy keeps track of
active Subscriptions in the `ScheduledAnnotationBeanPostProcessor`,
in order to cancel them all in case of shutdown.
The existing scheduling support for tasks is reused, aligning the
triggering behavior with the existing support: cron, fixedDelay and
fixedRate are all supported strategies.
If the `Publisher` errors, the exception is logged at warn level and
otherwise ignored. As a result new `Runnable` instances will be
created for each execution and scheduling will continue.
The only difference with synchronous support is that error signals
will not be thrown by those `Runnable` tasks and will not be made
available to the `org.springframework.util.ErrorHandler` contract.
This is due to the asynchronous and lazy nature of Publishers.
