- Added org.springframework.http.StreamingHttpOutputMessage, which
allows for a settable request body (as opposed to an output stream).
- Added http.client.HttpComponentsStreamingClientHttpRequest, which
implements the above mentioned interface, mapping setBody() to a
setEntity() call on the Apache HttpClient HttpEntityEnclosingRequest.
- Added a 'bufferRequestBody' property to the
HttpComponentsClientHttpRequestFactory. When this property is set to
false (default is true), we return a
HttpComponentsStreamingClientHttpRequest instead of a (request
buffering) HttpComponentsClientHttpRequest.
Issue: SPR-10728
SPR-10402 in Spring Framework 3.2.3 treated empty request parameter
values as missing values, if the empty value was turned into a null
by a PropertyEditor or Converter. This caused the regression.

Similar to @ExceptionHandler but for message processing. Such a method
can send messages to both the message broker channel and the client
channel provided the client is subscribed to the target destination.
Previously DeferredResult locked around the setting of the result
including handling up to the part of submitting a dispatch. This
can cause a deadlock if a timeout occurs at the same time since
the Tomcat timeout thread has its own locking that permits only
one thread to do timeout or dispatch processing.
The fix reduces the locking to cover only the attempt to set the
DeferredResult but not the dispatching.

Spring 3.2.2 introduced a change to avoid closing the response stream
in HttpMessageConverters (SPR-10095). However, the InputStream of
resources being written, for example as part of a multi-part request
should be closed. This change ensures that.
Issue: SPR-10460
If type conversion turns an empty request parameter value (i.e. "") to
null, we should treat it as a missing value. By default the
ConversionService doesn't change empty strings and therefore one must
explicitly convert them to null for example by registering a
StringTrimmerEditor with emptyAsNull=true.
Issue: SPR-10402
Previously ContentNegotiationManager continued with the next
ContentNegotiationStrategy only if the current one returned an empty
list. Now it also does that if the current ContentNegotiationStrategy
returns "*/*". Since the absence of an Accept header and "*/*" have
the same meaning, this allows a default content type to be used in
either case.
Issue: SPR-10513
Update ServletContextAwareProcessor to allow subclasses to support late
binding of the ServletConfig and/or ServletContext. Allows for the
post-processor to be registered before the servlet environment has been
initialized.
Issue: SPR-10381
Use LinkedHashMaps/Sets wherever exposed to users, and code tests defensively in terms of expected Map/Set ordering. Otherwise, there'll be runtime order differences between JDK 7 and JDK 8 due to internal HashMap/Set implementation differences.
Issue: SPR-9639
This is useful to make sure response headers are written to the
underlying response. It is also useful in conjunction with long
running, async requests and HTTP streaming, to ensure the Servlet
response buffer is sent to the client without additional delay and
also causes an IOException to be raised if the client has gone away.
- configure SockJS handler by type (as well as by instance)
- add method to obtain SockJS handler instance via SockJsConfiguration
- detect presense of jsr-356 and use it if available
