Prior to this commit, the `DefaultServerWebExchange` would attempt to
decode request bodies as form-data or multipart of the request
content-type was compatible with the expected media types.
If requests are sent with an invalid wildcard content-type such as "*/*"
or "multipart/*", we should not attempt to decode here.
Fixes gh-34660
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.

AbstractKotlinSerializationHttpMessageConverter#getSupportedMediaTypes(Class<?>)
currently invokes transitively supports(Class<?>) which always return false
with generic types.
This commit adds an override that just invokes getSupportedMediaTypes().
Closes gh-34992
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
Prior to this commit, the JAXB message converters would only rely on the
encoding declaration inside the XML document for reading the document.
This would then use the default UTF-8 encoding, even if the HTTP message
has the `"application/xml;charset=iso-8859-1"` Content-Type.
This commit ensures that both `Jaxb2CollectionHttpMessageConverter` and
`Jaxb2RootElementHttpMessageConverter` use the encoding declared in the
HTTP Content-Type, if present.
Fixes gh-34745
As of gh-33806, the HttpComponents client request factory is forward
compatible with the 5.4+ versions of that library for configuring HTTP
request configuration.
This change would not tkae into account configuration set at the Spring
level because it would consider the default `RequestConfig` instance as
a custom one. This commit ensures that Spring sets its own configuration
if no custom configuration was set for all supported HttpComponents
generations.
Fixes gh-34851
This commit makes AbstractJackson2HttpMessageConverter#getObjectMappersForType
return value non nullable as an empty map is returned in case of no

Before RfcUriParser we expected opaque URI's to not have ":/"
after the scheme while the new parser expect opaque URI's to
not have a slash anywhere after the scheme. This commit
restores the previous behavior.
