Prior to this commit, the WebFlux server support would try reading
form-data from the request by:
* first, checking that request content-type is compatible with a
form-data content-type
* then by selecting a message reader that is compatible with the given
request content-type
This approach is flawed because if the content-type provided by the
request is too broad, another message reader could be selected that's
not meant to be used for reading form-data. Typically, a JSON message
reader could be selected and would fail when reading the request.
This problem was previously hidden because message readers would not
support `MultiValueMap` as a target type. Now that some readers support
this type, this can lead to deserialization errors.
This commit now ensures that in all cases, we attempt to read form-data
with a message reader that supports the
"application/x-www-form-urlencoded" media type.

Prior to this commit, the "filename" parameter value for the
"Content-Disposition" header would contain non-printable characters,
causing parsing issues for HTTP clients.
This commit ensures that all non-printable characters are encoded.

Previously, when saving a WebSession, the system did not check whether
the session ID already existed. As a result, even if the session being
saved was an update to an existing one, it was incorrectly treated as a
new session, and a "maximum sessions exceeded" error was triggered.
This fix ensures that if a WebSession with the same ID already exists,
it will be updated rather than counted as a new session, thereby
preventing unnecessary session limit violations.

supported return types for `@ExceptionHandler` methods.

AbstractKotlinSerializationHttpMessageConverter#getSupportedMediaTypes(Class<?>)
currently invokes transitively supports(Class<?>) which always return false
with generic types.
This commit adds an override that just invokes getSupportedMediaTypes().

Prior to this commit, combining the "/*" and "/x/y" path patterns
would result in a `StringIndexOutOfBoundsException`.
This commit fixes this problem and revisits the implementation for
better consistency:
* "/*" + "/x/y" is now "/x/y"
* "/x/*.html" + "/y/file.*" is now rejected because they don't share the
same prefix.
This change also adds the relevant Javadoc to the `PathPattern#combine`
method.

Prior to this commit, we would use the
`java.net.http.HttpRequest.Builder#method(String, BodyPublisher)` to
create HTTP requests for the JDK HttpClient. This method requires a
non-null body publisher; providing an empty publisher writes a
"Content-Length: 0" header to all requests.
As of Java 19, this behavior changes for `HttpRequest.Builder#GET` and
similar methods, where the body publisher is considered as null and no
"Content-Length" header is written.
This commit aligns with this behavior and favors dedicated HTTP methods
whenever available.`
Closes gh-34971
