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.

This commit adds support of parsing a simple long from a String and
turning it to an `Instant` by considering it represents a timestamp in
milliseconds (see `Instant.ofEpochMilli`). Failing to parse a long from
the String, the previous algorithm is used: first check for an RFC-1123
representation then an ISO_INSTANT representation.
See gh-30312
Closes gh-30546
Prior to this commit, if a non-annotated [1] class was registered
directly with an ApplicationContext -- for example, via
AnnotatedBeanDefinitionReader, AnnotationConfigApplicationContext, or
@ContextConfiguration -- it was not considered a configuration class in
'lite' mode unless @Bean methods were declared locally. In other words,
if the registered class didn't declare local @Bean methods but rather
extended a class that declared @Bean methods, then the registered class
was not parsed as a @Configuration class in 'lite' mode, and the @Bean
methods were ignored.
Whereas, a non-annotated class registered via @Import is always
considered to be a configuration class candidate.
To address this discrepancy between @Import'ed classes and classes
registered directly with an ApplicationContext, this commit treats any
class registered via AnnotatedBeanDefinitionReader as a @Configuration
class candidate with @Bean 'lite' mode semantics.
[1] In this context, "non-annotated" means a class not annotated (or
meta-annotated) with @Component, @ComponentScan, @Import, or
@ImportResource.

This commit:
- Refine the wording used in logs and Javadoc
- Avoid calling awaitPreventShutdownBarrier() in afterRestore()
- Add logs to print the restart duration
See gh-29921
Restores proper event type propagation to parent context.
Selectively applies payload type to given payload object.
Also reuses cached type for regular ApplicationEvent now.
Closes gh-30360
This commit fixes the check by avoiding a fallback to eventType's
hasUnresolvableGenerics(). This could previously lead to checking a
generic event type `A<T>` against a listener which accepts unrelated
`B` and return `true` despite the inconsistency.
Note that this wouldn't necessarily surface to the user because there is
a `catch (ClassCastException e)` down the line, which was primarily put
in place to deal with lambda-based listeners but happens to catch an
exception thrown due to the bad result of `supportsEventType`.
The `supportsEventType` now matches generic `PayloadApplicationEvent`
types with a raw counterpart, using the above fallback only in that case
and otherwise ultimately returning `false`.
Closes gh-30399
This commit reviews BeanInstanceSupplier to reuse more code from
ConstructorResolver. Previously, the autowired argument resolution was
partially duplicated and this commit introduces a new common path via
RegisteredBean#resolveAutowiredArgument.

VirtualThreadDelegate built on JDK 21 for multi-release jar.
Includes dedicated VirtualThreadTaskExecutor as lean option.
Includes setVirtualThreads flag on SimpleAsyncTaskExecutor.
Includes additional default methods on AsyncTaskExecutor.
Closes gh-30241
This commit handles AutowiredCandidateQualifier instances, rather than
relying on qualifiers being statically defined and meta-annotated with
`@Qualifier`.
Closes gh-30410
This commit enables sub-classes to better customize resource selection
and resource loading in `ReloadableResourceBundleMessageSource`, without
a need to duplicate the caching logic of `refreshProperties`.
See gh-30334
Closes gh-30369
This commit optimizes `DefaultLifecycleProcessor::stopBeans` by using a
`TreeMap` when gathering the `LifecycleGroup`s during stopBeans. It also
switches to a functional style using `computeIfAbsent`.
Finally, it further optimizes `LifecycleGroup` by removing sorting of
`LifecycleGroupMember` members list entirely, turning the class into a
simple record.
This is possible because the members list is already comprised of
members which all share the same phase value, so sorting according to
each member's phase is redundant.

- Split Validator::of into two factory methods:
- forInstanceOf using Class::isAssignableFrom
- forType using Class::equals
- Moved anonymous implementation into TypedValidator with default access
Closes gh-30341
This commit introduces `of` method in `Validator` to provide a way to
create a validator for the specific type `<T>` using `BiConsumer<T, Errors>`
and define the validator in a functional way.
This also eliminates the boilerplate for implementing the `supports` method.
ObjectUtils.nullSafeToString(Object) exists for generating a string
representation of various objects in a "null-safe" manner, including
support for object graphs, collections, etc.
However, there are times when we would like to generate a "concise",
null-safe string representation that does not include an entire object
graph (or potentially a collection of object graphs).
This commit introduces ObjectUtils.nullSafeConciseToString(Object) to
address this need and makes use of the new feature in FieldError and
ConversionFailedException.
Closes gh-30286
This commit refactors some AssertJ assertions into more idiomatic and
readable ones. Using the dedicated assertion instead of a generic one
will produce more meaningful error messages.
For instance, consider collection size:
```
// expected: 5 but was: 2
assertThat(collection.size()).equals(5);
// Expected size: 5 but was: 2 in: [1, 2]
assertThat(collection).hasSize(5);
```
Closes gh-30104
