Bean-derived null values may still get passed into bean properties and injection points but only if those are declared as non-required. Note that getBean will never return null; a manual bean.equals(null) / "null".equals(bean.toString()) check identifies expected null values now. This will only ever happen with custom FactoryBeans or factory methods returning null - and since all common cases are handled by autowiring or bean property values in bean definitions, there should be no need to ever manually check for such a null value received from getBean.

The PathPattern compareTo method is now consistent with equals when
two patterns are of the same specificity but otherwise different.
Separately PathPattern now exposes a Comparator by specificity that
offers the current functionality of compareTo. This can be used for
actual sorting where we only care about specificity.
Consistent behavior with matches(PathContainer), the two had slightly
different logic for handling of empty paths.
Make matchAndExtract independantly usable without the need to call
matches(PathContainer) first. Essentially no longer raising ISE if the
pattern doesn't match but simply returning null.
Rename getPathRemaining to matchStartOfPath since the method does
match and to be more clear about what the method and the return value
intuitively follows.
Remove matchStart which matches the start of the pattern (rather than
the start of the path). It is a use case that does not come up in
request mapping.
This commit changes the WebClient so that it now throws a
`WebClientResponseException` for `ResponseSpec.bodyTo`. This newly
introduces exception contains the status code, headers, and body of the
response message.
As a consequence of the above, we had to change `onStatus` so that the
`exceptionFunction` now returns a `Mono<Throwable>` rather than a
`Throwable`, which it was before. The Mono allows for asynchronous
operations, such as reading the contents of the body.

Remove the separator constructor argument (but preserve internal
functionality) now that PathPatternParser is more explicitly purposed
for URL paths and in any case the use of an alternate separator would
also requires a similar input option on the PathContainer parsing side.
Re-arrange the checks so that if there is no form parameter, then
immediately and unconditionally delegate to super.getParameterValues().
Or reversely if there is no super.getParameterValues() then return the
form parameter.
So the only remaining case is when combining values present in both.
In that case we'll take both only if a queryString exists.
One extra fix is to not even wrap the request if we did not parse any
form parameters at all which can happen with HttpHiddenMethodFilter.

This commit also removes WebFlux non-extension functions in favor of
regular Kotlin extensions leveraging ParameterizedTypeReference parameter.

When the input stream is a JSON array the tokenizer skips over the
start and end array tokens in order to decode into an array of
top-level objects. However in this mode it also skips over nested
start and end array tokens which prevents proper parsing of JSR-310
dates (represented with an array syntax) as well as any fields that
are collections.

The method was orginally added under SPR-14547 but the example in it
was probably intended for use with Content-Disposition server response
header (file dowonload) and not for a Content-Disposition header
within the body of a multipart request.
In a Spring application a multipart request is typically serialized
by the FormHttpMessageConverter and hence the Content-Disposition is
not explicitly set by the application.

This commit parses the "Host" HTTP request header as an
`InetSocketAddress`, while supporting IPv6 addresses like `[::1]`.
This host string contains `:` chars even though it has no port
information.
Issue: SPR-15799
StandardMultipartHttpServletRequest now properly decodes RFC-5987
encoded filenames (i.e. filename*) by delegating to ContentDisposition
and also support RFC-2047 syntax through javax.mail MimeUtility.

This commit updates BeanUtils class in order to add Kotlin optional
parameters with default values support to the immutable data classes
support introduced by SPR-15199.
Issue: SPR-15673
Prior to this commit, the host+port information of the incoming request
where taken from the remoteAddress, which is actually the socket address
of the HTTP client (i.e. not the server).
This commit resolves this information from the "Host" HTTP request
header, if available, or the actual local address of the channel if no
header is available.
