This is a follow-up change related to gh-31104.
This change reverts the changes previously made in
`ExceptionHandlerExceptionResolver` and instead attempts to reset the
response directly in `DispatcherServlet` in order to cover all types or
exception handling.
Unlike the previous change, we decided to continue even if the response
was already committed: exception handlers will have a chance to be
called, even if it means they'll have to operate on a garbled response.
This change will cause less disruption, in case existing exception
handlers were relying on this behavior.

Prior to this commit, the Spring Framework build would publish several
zip artifacts:
* a "*-schema.zip" containing all the XSD schemas produced
* a "*-docs.zip" containing the API docs
* a "*-dist.zip" containing all of the above, plus module jars
Since the reference docs are now produced by Antora in a separate
process, the "*-docs.zip" does not contain the reference docs anymore.
But it still contains the API docs which are automatically fetched from
the artifact repository and published on the docs.spring.io website.
This commit intends to update the current arrangement and optimize the
build.
First, the "*-dist.zip" is not published anymore, since it cannot be
consumed anyway by the community: repo.spring.io does not distribute
release artifacts publicly, developers are expected to get them from
Maven Central. This arrangement is quite dated anyway and is not really
useful in current application build setups.
The generation of API docs is moved to a new "framework-api" module,
separating it from the reference docs module ("framework-docs") which
contains Java, Kotlin and Asciidoctor sources. This removes the custom
javadoc aggregation task and instead uses a dedicated Gradle plugin.
This change also adds a new `-PskipDocs` Gradle project property that
skips entirely the documentation tasks (javadoc, kdocs) as well as the
"distrbution" tasks managed in the framework-api module.
This allows developers to publish locally a SNAPSHOT of Spring Framework
without creating the entire documentation distribution. This is
particularly useful for local testing.
For example, `$ ./gradlew pTML -PskipDocs`.
Closes gh-31049
Prior to this commit, the `ExceptionHandlerExceptionResolver` would
resolve exceptions and handle them by writing to the HTTP response body,
even if the request was already partially handled and content was
written to the response body.
This could result in HTTP responses with some content for the intended
application response, then other content for the handled exception.
This would happen especially when the error would be raised while
writing to the response (for example when serializing content).
This commit attempts to reset the HTTP response before handling the
exception. This effectively resets the response buffer for the body as
well as response headers. If the response is already committed, the
Servlet container raises an exception and the exception handling is
skipped altogether in order to avoid garbled responses.
Closes gh-31104
Prior to this commit, `@Async` and `@EventListener` annotated methods
would lose the the logging and observation contexts whenever their
execution was scheduled on a different Thread.
The Context Propagation library supports this use case and can propagate
context values in ThreadLocals, Reactor Context and more.
This commit introduces a new `TaskDecorator` implementation that
leverages the Context Propagation library. When configured on a
`TaskExecutor`, this allows to properly propagate context value through
the execution of the task.
This implementation is completely optional and requires the
"io.micrometer:context-propagation" library on the classpath. Enabling
this feature must be done consciously and sometimes selectively, as
context propagation introduces some overhead.
Closes gh-31130
When use of the deprecated feature is detected, a WARNING log message
will be generated analogous to the following.
WARN o.s.c.a.AnnotationBeanNameGenerator - Support for convention-based
stereotype names is deprecated and will be removed in a future version
of the framework. Please annotate the 'value' attribute in
@org.springframework.context.annotation.AnnotationBeanNameGeneratorTests$ConventionBasedComponent1
with @AliasFor(annotation=Component.class) to declare an explicit alias
for @Component's 'value' attribute.

Closes gh-31093
This commit schedules blocking I/O operations on the bounded elastic
scheduler, which includes retrieving the content length and writing
the resource (region).

This commit builds on the recently added support for using @AliasFor to
override the `value` attribute in `@Component, and allows a custom
component name to be specified in both @ControllerAdvice and
@RestControllerAdvice via new `name` attributes.

Closes gh-21108

Make sure NoUniqueBeanDefinitionException to be serializable
Closes gh-29753
Although gh-20615 introduced the use of @AliasFor for @Component(value) in the built-in
stereotype annotations (@Service, @Controller, @Repository, @Configuration, and
@RestController), prior to this commit the framework did not actually rely on @AliasFor
support when looking up a component name via stereotype annotations. Rather, the
framework had custom annotation parsing logic in
AnnotationBeanNameGenerator#determineBeanNameFromAnnotation() which effectively ignored
explicit annotation attribute overrides configured via @AliasFor.
This commit revises AnnotationBeanNameGenerator#determineBeanNameFromAnnotation() so that
it first looks up @Component stereotype names using @AliasFor semantics before falling
back to the "convention-based" component name lookup strategy.
Consequently, the name of the annotation attribute that is used to specify the bean name
is no longer required to be `value`, and custom stereotype annotations can now declare an
attribute with a different name (such as `name`) and annotate that attribute with
`@AliasFor(annotation = Component.class, attribute = "value")`.

scanning.
