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.

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
