The Javadoc on tag classes now has all the information including a
list of all tags at the package level, HTML tables listing tag
attributes in each tag class, and class level description that is
as good or in many cases better than what was in the reference.

1. Move schemas to local appendix within each top-level section.
2. Link to Javadoc for JSP tags
3. Purge Class Spring usage information

The WebTestClient now takes advantage of the support for decoding
response to Void.class in WebClient so that applications can use
expectBody(Void.class) to the same effect as using
response.bodyToMono(Void.class) as documneted on WebClient#exchange.
The top-level, no-arg returnResult method (added very recently) has been
retracted, since the use of returnResult at that level, i.e. without
consuming the response content, should be used mainly for streaming.
It shouldn't be used for "no content" scenarios.
Documentation and Javadoc have been udpated accordingly.
Use the ClientResponse methods bodyToMono and bodyToFlux rather than
passing in a BodyExtractor so that WebTestclient now also benefits from
the recently improved handling of Void.class.
Before this commit those were burried in the Appendix where few would
guess to look. Previously that information was at the top, so it makes
sense to point to the Github wiki from the index HTML page.
Also a general update of the index page. Since we have recently revised
the overview, we can simply point to it and keep it shorter.
The section listing now includes more details per section.
Before this commit WebClient documentation was also included from the
Integration section where the RestTemplate is documented. That is
convenient but results in duplicate content under different URLs.
This commit removes the include from the Integration section and leaves
Concrete server and client, reactive request and response
implementations should not have to be accessed outside their package.
They could be seen as private to their HttpHandler adapters and
ClientHttpConnector's respectively.
The one exception, WebSocket upgrades in spring-webflux, is an internal
framework use case, accommodated via downcast + accessors in the
abstract base classes.
Prior to this commit, the `WebClient` always throws a `ClassCastException`
when an error occurs in `bodyToMono(ParameterizedTypeReference)``, and
not the expected exception, as set up by `onStatus`
Issue: SPR-16025
Extract WebClient content into a separate file that is now included
both in the WebFlux and in the Integration sections.
This allows having RestTemplate and WebClient documented in one place
under Integration while also keeping the same included in the WebFlux
section too.
Prior to this commit, asking for a `Void` type using any of the
`ClientResponse#bodyTo*` methods would immediately return an empty
`Publisher` without consuming the response body.
Not doing so can lead to HTTP connection pool inconsistencies and/or
memory leaks, since:
* a connection that still has a response body being written to it cannot
be properly recycled in the connection pool
* incoming `DataBuffer` might not be released
This commit detects when `Void` types are asked as body types and in
those cases does the following:
1. Subscribe to the response body `Publisher` to allow the connection to
be returned to the connection pool
2. `cancel()` the body `Publisher` if the response body is not empty; in
that case, we choose to close the connection vs. consume the whole
response body
Those changes imply that `ClientHttpResponse` and other related
contracts don't need a `close()` method anymore.

Includes unified detection of Kotlin's optional parameters in MethodParameter.isOptional(), reduces BeanUtils.findPrimaryConstructor to Kotlin semantics (for reuse in AutowiredAnnotationBeanPostProcessor), and finally introduces a common KotlinDetector delegate with an isKotlinType(Class) check.
