Until this change a single classloader was used to load
all compiled SpEL expressions. This meant in a context where an
expression was repeatedly flipping between compiled and interpreted
mode (which can happen if in MIXED mode compilation and changing
the context around the evaluation) the classloader would continually
load a new compiled version but not orphan the old compiled version.
This eventually uses up all the memory as the number of classes
is ever increasing.
With this change classloaders are used to load 100 compiled
expressions. The 101st will be loaded by a new one. Orphaning the
old classloader means if an expression is ever recompiled there
is more likely to be no anchored references left to the older
compiled form and it can be GC'd. In the MIXED situation above it
should help alleviate the problem of older classes never being
candidates for GC.

This commit changes the handling of 4xx/5xx status codes in the
WebClient to the following simple rule: if there is no way for the user
to get the response status code, then a WebClientException is returned.
If there is a way to get to the status code, then we do not return an
exception.

This commit renames `WebClient.ResponseSpec.bodyToEntity` to `toEntity`
and similarly renames `WebClient.ResponseSpec.bodyToEntityList` to
`toEntityList`. In both cases, the `body` prefix was dropped because the
return value contains more than the body.

- Fixed AnnotationUtils.getValue() operation to ensure it re-throws AnnotationConfigurationException instead of swallowing it (as it is done in few other operations in AnnotationUtils)
- Added test
- Removed unnecessary '@SuppressWarnings("unchecked")'
According to RFC-6265 that there should be a space between the ; and
the attribute name, i.e. the header should be something like
name=value; Domain=localhost; HttpOnly rather than
name=value;Domain=localhost;HttpOnly

Spring MVC now treats Flux<String> + "application/json" as (serialized)
text to be written directly to the response as is. This is consistent
with the rendering of String + "application/json".

This commit renames the `body(Object)` on ServerResponse to
`syncBody(Object)`. The reason for this is that the original method
name clashed with the `body(Publisher)` method in the Kotlin extension.
The new name nicely reflects the synchronous nature of the method,
making it less appealing than the `Publisher`-based `body` method.

Due to a bug in Rouge thats prevents it from working on MS Windows, we
are currently reverting back to CodeRay for source code highlighting
within the Reference Manual.

This commit adds the ability for path patterns to automatically
match a trailing separator (so there is no need to add two
variants of a pattern, one with and one without). This behaviour
is currently turned off but a simple tweak in PathPatternParser
can make it the default. If made default other parts of Spring
may need altering (simplifying hopefully) to cope with this.
