Commit 84714fbae9 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".

SmartHttpMessageConverter is similar to GenericHttpMessageConverter,
but more consistent with WebFlux Encoder and Decoder contracts, with
the following differences:
- A ResolvableType parameter is used instead of the Type one
- The MethodParameter can be retrieved via the ResolvableType source
- No contextClass parameter
- `@Nullable Map<String, Object> hints` additional parameter for write
and read methods
This commit also refines RestTemplate#canReadResponse in order to use
the most specific converter contract when possible.

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
Prior to this commit, WebFlux had Protobuf codecs for managing the
`Message`/`"application/x-protobuf"` encoding and decoding.
The `com.google.protobuf:protobuf-java-util` library has additional
support for JSON (de)serialization, but this is not supported by
existing codecs.
This commit adds the new `ProtobufJsonEncode` and `ProtobufJsonDecoder`
classes that support this use case. Note, the `ProtobufJsonDecoder` has
a significant limitation: it cannot decode JSON arrays as
`Flux<Message>` because there is no available non-blocking parser able
to tokenize JSON arrays into streams of `Databuffer`. Instead,
applications should decode to `Mono<List<Message>>` which causes
additional buffering but is properly supported.
Closes gh-25457
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
This commit compiles our Protobuf against 4.27, effectively raising our
baseline to 3.9+.
This commit also re-generates all the Java messages from the .proto spec
using the latest protoc binary.
Closes gh-33011
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
This commit adds support for the "Partitioned" cookie attribute in
WebFlux servers and the related testing infrastructure.
Note, Undertow does not support this feature at the moment.
Closes gh-31454
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
