Prior to this commit, RestTemplate and HttpMessageConverterExtractor did
not validate that the supplied HttpMessageConverter list contained no
null elements, which can lead to a NullPointerException when the
converters are accessed.
This commit improves the user experience by failing immediately if the
supplied HttpMessageConverter list contains a null element. This applies
to constructors for RestTemplate and HttpMessageConverterExtractor as
well as to RestTemplate#setMessageConverters().
Note, however, that RestTemplate#getMessageConverters() returns a mutable
list. Thus, if a user modifies that list so that it contains null values,
that will still lead to a NullPointerException when the converters are
accessed.
This commit also introduces noNullElements() variants for collections in
org.springframework.util.Assert.

This commit makes sure that in DefaultMultipartMessageReader's
DefaultFilePart, the file is not closed before all bytes are written,
by using DataBufferUtils.write (see c1b6885191d6a50347aeaa14da994f0db88f26fe).
The commit also improves on the logging of the
DefaultMultipartMessageReader.
Closes gh-23130
Prior to this commit, MockHttpServletRequest.setCookies() produced one
Cookie header per supplied cookie, resulting in multiple Cookie headers
which violates the specification.
This commit fixes this by ensuring that all cookie name-value pairs are
stored under a single Cookie header, separated by a semicolon.
Closes gh-23074
This commit allows to configure a custom path separator when parsing and
matching path patterns with `PathPatternParser`, but also when parsing
incoming paths as `PathContainer` instances.

1. Add contentType and filename options to PartBuilder.
2. Revert recently committed #44659f since asyncPart can't properly
support Publisher of Part (only Mono, can't support filename), and
replace that with support for Part in the regular part method.
Closes gh-23083
This commit adds a new constructor to `JettyClientHttpConnector` and
deprecates another one. Jetty is not creating `HttpClient` instances
using a builder API, but rather setting immutable configuration at
constructor time and using setters for the rest.
This commit addresses that by deprecating the constructor variant
accepting a `Consumer` and just delegating to Spring's implementation
for setting the client resources as needed.
Closes gh-22977
This commit migrates to the MockitoJUnitRunner where sensible, which
will later allow for an easier migration to Mockito's extension for
JUnit Jupiter.
In addition, this commit deletes unnecessary stubbing for various mocks
and polishes test fixture setup in various test classes.
This commit introduces a getOrEmpty(String) method in HttpHeaders that
returns an immutable, empty list if no values are present for the
specified header name. This is provided as a convenience over the
existing get(String) method which returns null in such cases.
Closes gh-22949
