This metadata information is required for supporting libraries using
`sun.misc.Unsafe#allocateInstance(Class<?>)`, even though Spring
Framework is not using this feature.

To make an analogy to read phenomena for transactional databases, this
commit effectively fixes the "Phantom Read" problem for Bean Overrides.
A phantom read occurs when the BeanOverrideBeanFactoryPostProcessor
retrieves a set of bean names by-type twice and a new bean definition
for a compatible type has been created in the BeanFactory by a
BeanOverrideHandler between the first and second retrieval.

Prior to this commit, the injection of test Bean Overrides (for
example, when using @MockitoBean) could fail in certain scenarios if
overrides were created for nonexistent beans "by type" without an
explicit name or qualifier. Specifically, if an override for a SubType
was created first, and subsequently an attempt was made to create an
override for a SuperType (where SubType extends SuperType), the
override for the SuperType would "override the override" for the
SubType, effectively removing the override for the SubType.
Consequently, injection of the override instance into the SubType field
would fail with an error message similar to the following.
BeanNotOfRequiredTypeException: Bean named 'Subtype#0' is expected to
be of type 'Subtype' but was actually of type 'Supertype$Mock$XHb7Aspo'
This commit addresses this issue by tracking all generated bean names
(in a generatedBeanNames set) and ensuring that a new bean override
instance is created for the current BeanOverrideHandler if a previous
BeanOverrideHandler already created a bean override instance that now
matches the type required by the current BeanOverrideHandler.
In other words, if the generatedBeanNames set already contains the
beanName that we just found by-type, we cannot "override the override",
because we would lose one of the overrides. Instead, we must create a
new override for the current handler. In the example given above, we
must end up with overrides for both SuperType and SubType.

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 fixes a regression in PlaceHolderParser where it would no
longer resolve nested placeholders for a case where the fallback has a
placeholder itself.
This is due to the Part implementations and how they are structure, and
this commit makes sure that nested resolution happens consistently.
Closes gh-34020
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.

Spring Framework 7.0 will use a Kotlin 2 baseline, using the latest 2.x
release at the time of the release.
This commit upgrades Kotlin to 2.1.0, and Kotlin Serialization and
Coroutines accordingly.
Closes gh-33629
As a preparation to using a Kotlin 2 baseline, this commit stops using
Java code snippets in Kotlin ones in order to avoid redeclaration
errors.

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.

StandardWebSocketUpgradeStrategy is the common replacement on Tomcat, Undertow and all EE servers. JettyRequestUpgradeStrategy remains the preferred choice on Jetty.

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
