Since Spring Framework 5.2, @RestControllerAdvice registered with
MockMvc when using MockMvcBuilders.standaloneSetup() has no longer been
properly supported if annotation attributes were declared in the
@RestControllerAdvice annotation. Prior to 5.2, this was not an issue.
The cause for this regression is two-fold.
1. Commit 50c257794f refactored
DefaultListableBeanFactory so that findAnnotationOnBean() supports
merged annotations; however, that commit did not refactor
StaticListableBeanFactory#findAnnotationOnBean() to support merged
annotations.
2. Commit 978adbdae7 refactored
ControllerAdviceBean so that a merged @ControllerAdvice annotation
is only looked up via ApplicationContext#findAnnotationOnBean().
The latter relies on the fact that findAnnotationOnBean() supports
merged annotations (e.g., @RestControllerAdvice as a merged instance of
@ControllerAdvice). Behind the scenes, MockMvcBuilders.standaloneSetup()
creates a StubWebApplicationContext which internally uses a
StubBeanFactory which extends StaticListableBeanFactory. Consequently,
since the implementation of findAnnotationOnBean() in
StaticListableBeanFactory was not updated to support merged annotations
like it was in DefaultListableBeanFactory, we only see this regression
with the standalone MockMvc support and not with MockMvc support for an
existing WebApplicationContext or with standard Spring applications
using an ApplicationContext that uses DefaultListableBeanFactory.
This commit fixes this regression by supporting merged annotations in
StaticListableBeanFactory#findAnnotationOnBean() as well.

Prior to this commit, StaticListableBeanFactory.isSingleton() returned
false for singleton beans unless they were created by a FactoryBean.
StaticListableBeanFactory.isSingleton() now properly returns true for
all beans not created by a FactoryBean.

Prior to this commit, if a value existed at the specified JSON path but
had an incompatible type, the AssertionError thrown contained a message
stating that the value did not exist (i.e., "No Value at JSON Path"),
which was not only misleading but also technically incorrect.
This commit fixes the error message for such use cases. For example, the
AssertionError thrown in such use cases now resembles the following.
At JSON path "$.name", value <Lisa> of type <java.lang.String> cannot
be converted to type <byte[]>

Prior to this commit, calling reset() on MockHttpServletResponse did not
reset the `charset` field to `false` which could result in the
"Content-Type" header containing `;charset=null` which in turn would
result in errors when parsing the "Content-Type" header.
This commit resets the charset field to `false` in
MockHttpServletResponse's reset() method to avoid such errors.

PR gh-25429 brought it to our attention that there was a bug in
AnnotationScanner when using a non-null class filter that filtered out
classes; however, it turns out that there is no production code that
utilizes the package-private class filtering support.
This commit therefore removes all class filtering support from
AnnotationScanner since that functionality is effectively unused.

Prior to this commit, scanning for annotations resulted in an infinite
loop when using the INHERITED_ANNOTATIONS search strategy and a class
filter that filters out visited classes.
This commit avoids an infinite loop in AnnotationsScanner's
processClassInheritedAnnotations(...) method by skipping the current
level of the class hierarchy when the current source class has been
filtered out.

Prior to this commit, a Profiles instance created via Profiles.of() was
not considered equivalent to another Profiles instance created via
Profiles.of() with the exact same expressions. This makes it difficult
to mock invocations of Environment#acceptsProfiles(Profiles) -- for
example, when using a mocking library such as Mockito.
This commit makes Profiles instances created via Profiles.of()
"comparable" by implementing equals() and hashCode() in ParsedProfiles.
Note, however, that equivalence is only guaranteed if the exact same
profile expression strings are supplied to Profiles.of(). In other
words, Profiles.of("A & B", "C | D") is equivalent to
Profiles.of("A & B", "C | D") and Profiles.of("C | D", "A & B"), but
Profiles.of("X & Y") is not equivalent to Profiles.of("X&Y") or
Profiles.of("Y & X").

Prior to this commit, SocketUtils used System.currentTimeMillis() for
the seed for the java.util.Random instance used internally. The use of
the milliseconds value returned by currentTimeMillis() can lead to
collisions for randomly selected free ports for tests executing in
parallel on the same computer.
This commit therefore switches to System.nanoTime() for the Random seed
used in SocketUtils in an attempt to avoid such collisions for tests
executing in parallel in different JVMs on the same computer.

This commit makes sure that the StringHttpMessageConverter reads
input with "application/*+json" as Content-Type with the UTF-8
character set.
