Historically, @Configuration classes that did not declare @Bean
methods were allowed to be abstract. However, the changes made in
76a6b9ea79 introduced a regression that prevents such classes from
being abstract, resulting in a BeanInstantiationException. This change
in behavior is caused by the fact that such a @Configuration class is
no longer replaced by a concrete subclass created dynamically by CGLIB.
This commit restores support for abstract @Configuration classes
without @Bean methods by modifying the "no enhancement required" check
in ConfigurationClassParser.

Prior to this commit, if a String 'value' attribute of an annotation
was annotated with @AliasFor and explicitly configured to alias an
attribute other than @Component.value, the value was still used as the
@Component name, but the warning message that was logged stated that
the 'value' attribute should be annotated with
@AliasFor(annotation=Component.class). However, it is not possible to
annotate an annotation attribute twice with @AliasFor.
To address that, this commit revises the logic in
AnnotationBeanNameGenerator so that it issues a log message similar to
the following in such scenarios.
WARN o.s.c.a.AnnotationBeanNameGenerator - Although the 'value'
attribute in @example.MyStereotype declares @AliasFor for an
attribute other than @Component's 'value' attribute, the value is
still used as the @Component name based on convention. As of Spring
Framework 7.0, such a 'value' attribute will no longer be used as the
@Component name.

Prior to this commit, `CronExpression` would support Quartz-style
expressions with "Nth occurence of a dayOfWeek" semantics by using the
`TemporalAdjusters.dayOfWeekInMonth` JDK support. This method will
return the Nth occurence starting with the month of the given temporal,
but in some cases will overflow to the next or previous month.
This behavior is not expected for our cron expression support.
This commit ensures that when an overflow happens (meaning, the
resulting date is not in the same month as the input temporal), we
should instead have another attempt at finding a valid month for this
expression.
Fixes gh-34360
Due to changes in gh-19118, classes that contain @Lookup methods are
no longer required to be concrete classes for use with component
scanning; however, the reference documentation still states that such
classes must not be abstract.
This commit therefore removes the outdated reference documentation and
updates the corresponding Javadoc.

Closes gh-34367
This change ensures that DataBinder can bind constructor with a Map
parameter that has no nested properties, but just simple values like
a String: `someMap[0]=exampleString`.
Integration tests have been added to cover similar cases that use the
ServletRequestDataBinder.
Closes gh-34043
This commit fixes a regression introduced by gh-24560, when adding
execution metadata support for scheduled tasks. The
`OutcomeTrackingRunnable` would delegate to the actual runnable but
could also hide whether it implements the `SchedulingAwareRunnable`
contract.
This commit ensures that `OutcomeTrackingRunnable` always implements
that contract and delegates to the runnable if possible, or return
default values otherwise.
Fixes gh-34058
This commit restores the user class in generated RootBeanDefinition
instances. Previously the CGLIB subclass was exposed. While this is
important in regular runtime as the configuration class parser operates
on the bean definition, this is not relevant for AOT as this information
is internal and captured in the instance supplier.
Closes gh-33960
This commit restores the signature of instance suppliers that are
exposing a CGLIB proxy. While calling the CGLIB proxy itself, and
making it available in BeanInstanceSupplier, is needed internally, such
type should not be exposed as it is an internal concern.
This was breaking InstanceSupplier.andThen as it expects the public
type of the bean to be exposed, not it's eventual CGLIB subclass.
Closes gh-33998
Prior to this commit, the equals() implementation in AdvisedSupport's
MethodCacheKey only considered methods to be equal based on an identity
comparison (`==`), which led to duplicate entries in the method cache
for the same logical method.
This is caused by the fact that AdvisedSupport's
getInterceptorsAndDynamicInterceptionAdvice() method is invoked at
various stages with different Method instances for the same method:
1) when creating the proxy
2) when invoking the method via the proxy
The reason the Method instances are different is due to the following.
- Methods such as Class#getDeclaredMethods() and
Class#getDeclaredMethod() always returns "child copies" of the
underlying Method instances -- which means that `equals()` should be
used instead of (or in addition to) `==` whenever the compared Method
instances can come from different sources.
With this commit, the equals() implementation in MethodCacheKey now
considers methods equal based on identity or logical equality, giving
preference to the quicker identity check.

Prior to this commit, the reactive Scheduled tasks would be wrapped as a
`SubscribingRunnable` which does not implement a custom `toString`. This
would result in task metadata using the default Java `toString`
representation for those.
This commit ensures that the bean class name and method name are used
for this `toString`.
Closes gh-34010
This commit introduces a test which verifies how many times the
matches() method of a StaticMethodMatcherPointcut is invoked during
ApplicationContext startup as well as during actual method invocations
via the advice chain, which also indirectly tests the behavior of the
equals() implementation in AdvisedSupport.MethodCacheKey.
In addition, this commit revises BeanFactoryTransactionTests to assert
that a transaction is started for the setAge() method.

The log message for a NoClassDefFoundError is now a DEBUG level message
handled like a TypeNotPresentException and similar to the following.
DEBUG: Skipping validation constraint hint inference for class
org.example.CustomConstraint due to a NoClassDefFoundError for
com.example.MissingType

Prior to this commit, AOT processing for bean validation failed with a
NoClassDefFoundError for constraints with missing dependencies.
With this commit, the processing no longer fails, and a warning is
logged instead.

Prior to this commit, AOT processing for bean validation failed with a
StackOverflowError for constraints with fields having recursive generic
types.
With this commit, the algorithm tracks visited classes and aborts
preemptively when a cycle is detected.
