The method includes logic that is currently in
ViewResolutionResultHandler but fits well in BindingContext and also
includes the call to saveModel method from the InitBinderBindingContext
subclass, which was called too early until now from
RequestMappingHandlerAdapter before the model has been fully updated.
This mirrors a similar method in ModelFactory on the Spring MVC side
which also combines those two tasks.

Now that HttpClientAdapter is deprecated and replaced by HttpExchangeAdapter
and ReactorHttpExchangeAdapter, our tests should use the new contracts.
See gh-30117
To handle method validation errors in ResponseEntityExceptionHandler,
MethodValidationException and associated types should not depend on
Bean Validation. To that effect:
1. MethodValidationResult and ParameterValidationResult no longer make
the underlying ConstraintViolation set available, and instead expose
only the adapted validation errors (MessageSourceResolvable, Errors),
analogous to what SpringValidatorAdapter does. And likewise
MethodValidationException no longer extends ConstraintViolationException.
2. MethodValidationPostProcessor has a new property
adaptConstraintViolations to decide whether to simply raise
ConstraintViolationException, or otherwise to adapt the ConstraintViolations
and raise MethodValidationException instead, with the former is the default
for compatibility.
3. As a result, the MethodValidator contract can now expose methods that
return MethodValidationResult, which provided more flexibility for handling,
and it allows MethodValidationAdapter to implement MethodValidator directly.
4. Update Javadoc in method validation classes to reflect this shift, and
use terminology consistent with Spring validation in classes without an
explicit dependency on Bean Validation.

This commit adds support for Kotlin parameter default values
in handler methods. It allows to write:
@RequestParam value: String = "default"
as an alternative to:
@RequestParam(defaultValue = "default") value: String
Both Spring MVC and WebFlux are supported, including on
suspending functions.
Closes gh-21139
This commit introduces a Kotlin-specific implementation
of the ExchangeFilterFunction interface that allows for
using coroutines, similar to what CoWebFilter does on
server-side.
Closes gh-30650
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 ensures that any storage used for multipart handling only
gets cleaned up if multipart data is actually retrieved via
ServerWebExchange::getMultipartData.
Closes gh-30590
