The JDK has decent support for walking a file system (via the
FileSystem API in java.nio.file), but prior to this commit Spring still
used hand-rolled pre-Java 7 code. Also, in principle, FileSystem can be
an abstraction used to express any hierarchy of resources through their
URIs. This is a good fit with the Spring Resource abstraction, and for
instance would mean that GraalVM native images could potentially do
classpath scanning through a custom URI and FileSystem already provided
by GraalVM.
In light of the above, this commit overhauls the implementation of
PathMatchingResourcePatternResolver to use a java.nio.file.FileSystem
to find matching resources within a file system.
As a side effect, several obsolete `protected` methods have been
removed from PathMatchingResourcePatternResolver.

This commit improves GeneratedClass to support inner classes, allowing
them to be registered by name with a type customizer, as
GeneratedClasses does for top level classes.
BeanDefinitionMethodGenerator leverages this feature to create a
matching structure for configuration classes that contain inner classes.
Closes gh-29213
New methods in DefaultResponseCreator for adding headers and cookies,
for specifying the character encoding when setting a string body on
a response, which is useful when working in environments that do not
automatically assume UTF-8, such as integrating with legacy
applications from a new Spring one.
New methods in MockRestResponseCreators support extra commonly used
HTTP status codes, including some that occur when working in AWS,
CloudFlare, or when using gateways such as Kong, where resilient
applications should be able to respond to ratelimits, gateway errors,
and gateway timeouts that may occur if a remote service is down.
Added test cases for any changes made.

This commit isolates the invocation of Kotlin coroutines into a separate
template method, so that it can be overridden in subclasses of
RequestMappingHandlerAdapter.
Closes gh-27195
This commit adds an overloaded version of invokeSuspendingFunction
that specifies a CoroutineContext, instead of using
Dispatchers.Unconfined.
Closes gh-27193
This commit updates ClassNameGenerator so that it uses a ClassName for
its default target. This makes sure that a target that has been
generated can be used.

Prior to this commit, `ServletContextResource` could rely on
`ServletContext#getRealPath` to check whether a resource exists.
This behavior is not enforced on some Servlet containers, as this method
is only meant to translate virtual paths to real paths, but not
necessarily check for the existence of the file.
See https://bz.apache.org/bugzilla/show_bug.cgi?id=55837#c3 for a
rationale of this behavior in Tomcat.
This commit enforces an additional check, resolving the path as a `File`
and checking that is exists and is a file.
Closes gh-26707
In general, `Stream#toList()` is not a transparent replacement for
`.collect(Collectors.toList()))`, as the former returns an immutable
list.
This commit reverts some of those changes, where the returned `List`
instance was expected to be mutable.

Commit 9a180d1811 introduced Kotlin-based
JMH benchmarks which prevent spring-beans from being imported into the
Eclipse IDE.
This commit ensures that src/jmh/kotlin is imported in Eclipse with the
"test" attribute set.
See gh-24104
This refinement ensures the constructor is properly
accessible, avoid duplicating current logic and
provide a slightly faster implementation of the
Kotlin codepath.

After gh-29068, some Type instances can throw an
IllegalArgumentException. This commit catches them
properly to just return a null serializer in that
case.
Closes gh-29192
Prior to this commit, resource handling would not serve empty files and
return instead HTTP 404 responses. This would only happen for files
contained by JARs, but not on the filesystem.
This can be tracked to changes done in `AbstractFileResolvingResource`
where we avoid serving empty files for directories, see gh-21372.
This commit improves the `checkReadable` method to align this behavior
between file system and JAR files.
Closes gh-28850
