Prior to this commit, the `RestClient` instrumentation would create and
close observations for HTTP requests, but would not open an observation
scope for the lifetime of the exchange.
This means that custom `ClientHttpRequestInterceptor` and
`ResponseErrorHandler` would not get access to the current observation
scope in case of tracing, possibly leading to missing trace ids in logs.
This commit ensures that an observation scope is managed for the
lifetime of the HTTP exchange.
Fixes gh-33397
Before UnknownContentTypeException is thrown, it is added to the current
Observation but since UnknownContentTypeException is a
RestClientException, the exception is added again in one of the
catch blocks later on.
Closes gh-33347
ClientHttpResponse implements Closeable and the close method of
DefaultConvertibleClientHttpResponse also stops the current Observation.
Before this change exiting the try-with-resource block stopped the
Observation since it called close on ClientHttpResponse.
After this, there were multiple error and stop calls on the Observation
in the catch blocks after the Observation was already stopped
which is invalid.
This change reorders the flow by stopping the Observation in the
finally block (closing ClientHttpResponse) and not stopping
the Observation in any of the catch blocks.
Closes gh-33346
This commit implements modifyContextPath in ServletRequestPath and
apply the same logic of concatenating the servlet path with the
context path.
Closes gh-33251
This commit makes sure to consistently check that the content length
is not set above 2GB. Previously it was only checked in
setContentLength.
Closes gh-33256
This change tracks the multipart nature of the async request
within the `DispatcherServlet`, in the `WebAsyncManager`.
This allows for the second ASYNC dispatch to recognize the
multipart aspect and clean up the associated resources.
Closes gh-33161
This commit makes sure that JAXBContext.newInstance consistently use
the target class classloader to detect the necessary resources.
Previously, the current thread's context classloader was used, which
could lead to not finding the required JAXB components.

Commit 84714fbae9f335beb059753ee7d2a08653e6bb6c introduced usage of the
-Djava.locale.providers=COMPAT command-line argument for javac in order
to allow our JDK 20 builds to pass by using legacy locale data.
That was done to ensure that Date/Time formats using AM/PM produced a
standard space (" ") before the "AM" or "PM" instead of a narrow
non-breaking space (NNBSP "\u202F"), which was introduced in Java 20
due to adoption of Unicode Common Locale Data Repository (CLDR-14032).
This commit removes usage of the -Djava.locale.providers=COMPAT
command-line argument and updates all affected tests to:
- Use an NNBSP before "AM" or "PM" in input text when running on Java 20
or higher.
- Leniently match against any Unicode space character in formatted
values containing "AM" or "PM".

Prior to this commit, the fix for gh-32730 disabled the involvment of
the osbervation filter for async dispatches. Instead of relying on ASYNC
dispatches to close the observation for async requests, this is now
using an async listener instead: async dispatches are not guaranteed to
happen once the async request is handled.
This change caused another side-effect: because async dispatches are not
considered anymore by this filter, the observation scope is not
reinstated for async dispatches. For example, `ResponseBodyAdvice`
implementations do not have the observation scope opened during their
execution.
This commit re-enables async dispatches for this filter, but ensures
that observations are not closed during such dispatches as this will be
done by the async listener.
Fixes gh-33091
Prior to this commit, the fix for gh-32575 introduced cases where the
client observation would be stopped twice.
This commit ensures that `RestClient` observations are stopped only once
when the response is closed, or before throwing an unhanlded exception.
Fixes gh-33068
Prior to this commit, the isClientDisconnectedException() method in
DisconnectedClientHelper checked whether the message of the ultimate
exception in an exception chain contained one of the phrases "broken
pipe" or "connection reset by peer". However, that failed to match if
the exception message contained "Connection reset", which is the case
for the SocketException thrown by throwConnectionReset() in
sun.nio.ch.SocketChannelImpl.
This commit therefore replaces the "connection reset by peer" phrase
with "connection reset" in order to support all exception messages
containing "connection reset".
Closes gh-33064
This commit changes the use of HttpSessionRequiredException in
ModelFactory::initModel to an IllegalStateException, because the former
extends ServletException and cannot be used in WebFlux.
Closes gh-33043
Prior to this commit, the `ContentCachingRequestWrapper` could allocate
a `FastByteArrayOutputStream` block that was larger than the content
cache limit given as a consturctor argument. This was due to an
optimization applied in gh-31834 for allocating the right content cache
size when the request size is known.
Fixes gh-32987
Prior to this commit, the `ServerHttpObservationFilter` would support
async dispatches and would do the following:
1. start the observation
2. call the filter chain
3. if async has started, do nothing
4. if not in async mode, stop the observation
This behavior would effectively rely on Async implementations to
complete and dispatch the request back to the container for an async
dispatch. This is what Spring web frameworks do and guarantee.
Some implementations complete the async request but do not dispatch
back; as a result, observations could leak as they are never stopped.
This commit changes the support of async requests. The filter now
opts-out of async dispatches - the filter will not be called for those
anymore. Instead, if the application started async mode during the
initial container dispatch, the filter will register an AsyncListener to
be notified of the outcome of the async handling.
Fixes gh-32730
Commit d7970e4ab8 introduced support for JAXBElement in
Jaxb2XmlEncoder's encodeValue() method; however, canEncode() still
returned false for a JAXBElement element type.
This commit revises canEncode() so that it returns true for an element
type that is assignable from JAXBElement.

Closes gh-32977
Prior to this commit, #31870 added support for constraint annotations on
container elements for handler method argument validation. Supporting
this use case:
```
public void addNames(List<@NotEmpty String> names)
```
This commit does the same for `@Valid` annotation:
```
public void addPeople(List<@Valid Person> people)
```
Fixes gh-32964
Includes JAXBContext locking revision (avoiding synchronization) and consistent treatment of DocumentBuilderFactory (in terms of caching as well as locking).
