Previously ForwardedHeaderFilter would return the same StringBuffer for every invocation. This
meant that users that modified the StringBuffer changed the state of the HttpServletRequest.
This commit ensures that a new StringBuffer is always returned for ForwardedHeaderFilter.

With this change there is a new getPathRemaining() method on
PathPattern objects. It is called with a path and returns
the path remaining once the path pattern in question has
matched as much as it can of that path. For example if the
pattern is /fo* and the path is /foo/bar then getPathRemaining
will return /bar. This allows for a set of pathpatterns
to work together in sequence to match a complete entire path.

InvalidDefinitionException has been introduced in Jackson 2.9 to be
able to differentiate invalid data sent from the client (should still
generate a 4xx HTTP status code) from server side errors like beans with
no default constructor (should generate a 5xx HTTP status code).

Revise Javadoc on AsyncHandlerMethodReturnValueHandler to clarify its
main purpose is to prioritze custom async return value handlers ahead
of built-in ones. Also replace the interface from built-in handlers
which are prioritized already.
Remove DeferredResultAdapter and ResponseBodyEmitterAdapter --
introduced in 4.3 for custom async return value handling, since for
5.0 we will add built-in support for reactive types and the value of
these contracts becomes very marginal.

Restore the correct client-side default for whether StringDecoder
should split on new lines. It is true forthe server and false for the
client by default.
The regression was introduced in the recent refactoring:
f8a21ab11b (diff-0175d58138b2e8b2bec087ffe0495340)
This commit folds ServerHttpMessage[Reader|Writer] into its parent
HttpMessage[Reader|Writer] with the server methods pre-implemented
by default to be simple pass-through delegates.
Includes a new overloaded ModelAndView constructor with an HttpStatus argument, as well as a HandlerMethodArgumentResolverSupport refactoring (revised checkParameterType signature, actually implementing the HandlerMethodArgumentResolver interface).

StringDecoder can be created in text-only vs "*/*" mode which in turn
allows a more intuitive order of client side decoders, e.g. SSE does
not have to be ahead of StringDecoder.
The commit also explicitly disables String from the supported types in
Jackson2Decoder leaving it to the StringDecoder in "*/*" mode which
comes after. This does not change the current arrangement since the
the StringDecoder ahead having "*/*" picks up JSON content just the
same.
From a broader perspective this change allows any decoder to deal with
String if it wants to after examining the content type be it the SSE
or another, custom decoder. For Jackson there is very little value in
decoding to String which works only if the output contains a single
JSON string but will fail to parse anything else (JSON object/array)
while StringDecoder in "*/*" mode will not fail.

This commit changes the `MediaTypeFactory` to return
`Optional<MediaType>` (instead of a plain `MediaType`) for the
`getMediaType` methods.
Issue: SPR-14908
Instead of accepting List<Encoder|Decoder> and then look for the first
to support JSON, always expect a single JSON [Encoder|Decoder] and use
that unconditionally.
When writing use the nested ResolvableType instead of the Class of the
actual value which should better support generics.
Remove the SSE hint and pass "text/event-stream" as the media type
instead to serve as a hint. We are expecting a JSON encoder and using
it unconditionally in any case so this should be good enough.
This commit changes the `MockServletContext.getMimeType` method to use
`MediaTypeFactory` instead of JAF. It also adds a `addMimeType(String,
MediaType)` method to customize the mime types returned from said
method.
Issue: SPR-14908
This commit drops the Java Activation Framework dependency from the
MediaTypeFactory, in favor of parsing our own `mime.types` file, which
was obtained from Apache HTTPD.

Fold ResourceRegionHttpMessageWriter into ResourceHttpMessageWriter.
The latter was a private helper (not meant to be exposed) and the two
have much in common now sharing a number of private helper methods.
The combined class does not extend AbstractServerHttpMessageConverter
from which it was not using anything.
Internally the combined class now delegates directly to ResourceEncoder
or ResourceRegionEncoder as needed. The former is no longer wrapped
with EncoderHttpMessageWriter which is not required since "resource"
MediaType determination is a bit different.
The consolidation makes it easy to see the entire algorithm in one
place especially for server side rendering (and HTTP ranges). It
also allows for consistent determination of the "resource" MediaType
via MediaTypeFactory for all use cases.
ResourceRegionHttpMessageWriter no longer extends from
EncoderHttpMessageWriter freeing it to pass the correct content type
into the encoder.
Considering that the main benefit of EncoderHttpMessageWriter is to
deal with content type fallback cases, there is nothing to be missed.
Furthermore ResourceRegionHttpMessageWriter is a package private class
that is used internally within ResourceHttpMessageWriter and never
exposed externally as a an actual HttpMessageWriter.
Issue: SPR-15358
CompositeHttpHandler is public and called ContextPathCompositeHandler.
Also an overhaul of the Javadoc on HttpHandler, WebHttpHandlerAdapter,
and ContextPathCompositeHandler.
Extract CompositeHttpHandler to a package private class and add direct
support via `HttpHandler.of(...)`. This removes the need for the
`HttpHandlerAdapterSupport` class.
Currently the BOM versions are:
* reactor-core 3.0.6.BUILD-SNAPSHOT
* reactor-netty 0.6.2.BUILD-SNAPSHOT
This commit fixes as well a few deprecations in reactor-core.
The SSE reader is ordered ahead of StringDecoder because with
response.decodeToFlux(String.class) we actually want the SSE reader
to get involved first based on the content-type.
At the same time with response.decodeToMono(String.class) there is
nothing the SSE reader can do while the StringDecoder could read the
entore content as one String, as long as the server does terminate
the stream which can happen in a testing scenario.
This commit updates ServerSentEventHttpMessageReader#readMono in
to support String.class by delegating to StringDecoder. Since
reading to a Mono is an explicit choice there is not much possibility
for interfering with decoding to Flux.

From spring-webflux to spring-web test sources since it is perfectly
usable for testing Spring MVC annotation method support.
Potentially to be promoted further up for use in any module that has
annotation method support. It has spring-core dependencies only
Prior to this commit, the `ShallowEtagHeaderFilter` could participate in
the response and set its ETag/Content-Length headers, even for HEAD
requests. Since the response body is empty, the filter implementation
would set a `"Content-Length: 0"`.
The RFC states that responses to HEAD requests should exhibit identical
response headers to GET (with the possible exception of payload related
headers such as Content-Length.
With this commit, `ShallowEtagHeaderFilter` now ignores HEAD requests
since the proper values may be set already for payload related headers
by the handler. The filter has no way to generate a proper ETag value
nor calculate the content length without the actual body.
