Prior to this commit, repeated calls to `DataBuffer.write(CharSequence,
Charset)` would not write the given chars to the expected position in
the original buffer.
This commit fixes that by writing to the `outBuffer.position()`, offset
by the current `DataBuffer.writePosition()`.
Fixes gh-22484
Prior to this commit, `DataBuffer.write` would throw an
`IllegalStateException` when called with an empty `String`, since the
`CharsetEncoder` would be flushed on an incorrent state.
This commit skips entirely the encoding phase for empty `String`.
Fixes#22262
This allows for proper nested type conversion in @Value Optional fields analogous to method parameters, through a new TypeDescriptor-based method in the TypeConverter SPI. As an additional and less involved measure that is worth backporting, DefaultListableBeanFactory defensively checks for pre-converted Optional wrappers.

Aalto's InputFactoryImpl already disables loading of external entities
by default (property "javax.xml.stream.isSupportingExternalEntities").
This commit goes further by applying the same defensive measures as we
do elsewhere for XMLInputFactory, which disables DTD completely.
Arguably there is no good reason to enable that by default in WebFlux.
Typically a straight up equals as well as Collections#contains
checks for MediaType.ALL is susceptible to the presence of
media type parameters.
This commits adds equalsTypeAndSubtype as well as an
isPresentIn(Collection<MimeType>) methods to MimeType to faciliate
with checks for MediaType.ALL.

Prior to this commit, one could write a `CharSequence` to an existing
`DataBuffer` instance by turning it into a byte array or `ByteBuffer`
first. This had the following disadvantages:
1. Memory allocation was not efficient (not leveraging pooled memory
when available)
2. Dealing with `CharsetEncoder` is not always easy
3. `DataBuffer` implementations, like `NettyDataBuffer` can use
optimized implementations in some cases
This commit adds a new `DataBuffer#write(CharSequence, Charset)` method
for those cases and also an `ensureCapacity` method useful for checking
that the current buffer has enough capacity to write to it..
Issue: SPR-17558
Prior to this commit, parallel invocations of
MethodParameter.findParameterIndex() (invoked indirectly via
SynthesizingMethodParameter.forParameter() and
MethodParameter.forParameter()) could intermittently lead to an
IllegalArgumentException being thrown due to a race condition in the
internal implementation of the JDK's
java.lang.reflect.Executable.getParameters() method.
This commit addresses this issue by introducing a fallback for-loop
that iterates over the candidate parameters a second time using
equality checks instead of identity checks.
