Previously, the infrastructure provided by WebMvcConfigurationSupport
and WebFluxConfigurationSupport can lead to unexpected results due to
the lack of qualifier for certain dependencies. Those configuration
classes refer to very specific beans, yet their injection points do not
define such qualifiers. As a result, if a candidate exists for the
requested type, the context will inject the existing bean and will
ignore a most specific one as such constraint it not defined. This can
be easily reproduced by having a primary Validator whereas a dedicated
"mvcValidator" is expected. Note that a parameter name is in no way a
constraint as the name is only used as a fallback when a single
candidate cannot be determined.
This commit provides explicit @Qualifier metadata for such injection
points, renaming the parameter name in the process to clarify that it
isn't relevant for the proper bean to be resolved by the context.

Prior to this commit, Spring Framework would use `Schedulers.elastic()`
in places where we needed to process blocking tasks in a reactive
environment.
With reactor/reactor-core#1804, a new `Schedulers.boundedElastic()`
scheduler is available and achieves the same goal with added security;
it guarantees that resources are bounded.
This commit uses that new scheduler in the standard websocket client,
since the underlying API is blocking for the connection phase and we
need to schedule that off a web server thread.

Prior to this commit, the isSimpleProperty() and isSimpleValueType()
methods in BeanUtils treated void and Void as simple types; however,
doing so does not make sense in this context, since void implies the
lack of a property or value.
This commit addresses this by explicitly excluding void and Void in the
logic in isSimpleValueType().
This commit also simplifies the implementation of
ViewResolutionResultHandler.supports(HandlerResult) to take advantage
of this change.
Closes gh-23573
Prior to this commit, ClassUtils.isPrimitiveOrWrapper() and
ClassUtils.isPrimitiveWrapper() did not return true for Void.class.
However, ClassUtils.isPrimitiveOrWrapper() did return true for
void.class. This lacking symmetry is inconsistent and can lead to bugs
in reflective code.
See: https://github.com/spring-projects/spring-data-r2dbc/issues/159
This commit addresses this by adding an entry for Void.class -> void.class
in the internal primitiveWrapperTypeMap in ClassUtils.

This commit polishes tests in spring-aop by using
OrderComparator.sort() and lambda expressions instead of anonymous
classes where feasible.
Closes gh-23458
Previously DefaultWebClientBuilder always defaulted the ClientHttpConnector
with ReactorClientHttpConnector. This worked fine if reactor was used.
However, it would break if the user was trying to leverage Jetty.
This commit defaults to use Reactory Netty HttpClient if it is present. If
it is not present it then Jetty's HttpClient is used if present.
Closes gh-23491
The recently added body(Object) variant can be confused easily with
body(Publisher, Class) forgetting to provide the element type and
only running into the IllegalArgumentException at runtime.
