Prior to this commit, Spring WebFlux function would let
`DecodingException` thrown by codecs bubble up to the web handler level.
Since this exception is not handled by default there, the response would
be turned into a HTTP 500 status.
In the annotation model, `ArgumentResolver` implementations wrap this
exception with a `ServerWebInputException`, which itself extends
`ResponseStatusException`. The latter is supported by the error handling
infrastructure as a HTTP 400 response.
This commit ensures that `DecodingException` instances are properly
wrapped in `ServerWebInputException` at the `ServerRequest` level
directly, thus supporting all setup modes ("standalone" and through the
`DispatcherHandler`).
Fixes#22290
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.

Commit #93b7a4 added support for pre-configuring URI variables at the
UriComponentsBuilder level, and also changed toUriString to encode
template and URI variables separately. However this went a bit too far
causing side effects for URLs with curly braces that don't represent
URI variables.
This commit restores the original toUriString behavior which is to
encode template and URI variables sepraately only if URI variables have
been pre-configured.
Issue: SPR-17630
The xml parser does not fill in defaults provided in the XSD when
validation is disabled. As a result, attributes like default-lazy-init
will not receive the value "default" but an empty string.
With this commit, BeanDefinitionParserDelegate now takes this into
account, checking default values against empty string as well as
"default".
As a consequence, default-lazy-init attribute should now work correctly
even when the XSD validation is disabled.
Issue: SPR-8335
Reactor is now building its Javadoc with a recent JDK version, which
changes the structure of the published HTML pages.
Without this change, the build fails during the Dokka generation with
the following exception:
```
Exception while loading package-list from
ExternalDocumentationLinkImpl(
url=http://projectreactor.io/docs/core/release/api/,
packageListUrl=http://projectreactor.io/docs/core/release/api/package-list)
```
This commit now points to the `/element-list` page, which seems to
contain the same information as the `package-list` page.
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.
