WebSocket clients going away is an expected and common occurance.
Logging at ERROR level on failure to close a connection or on failures
to write data to a WebSocket sessions has a high potential for false
positives with very little to do. This change lowers the log level for
a number of log messages that fit this category.
This should be helped by the effort already spent for 4.1 to ensure
logging at DEBUG level doesn't produce excessive amounts of logging.

Refine the logic introduced in commit 71c6eb2b so that additional
imported @Configuration classes are not considered as candidates if
they have already been parsed.

Prior to this commit, the `ProtobufHttpMessageConverter` would call
`outputMessage.getBody()` at the beginning of the `writeInternal`
method, thus writing HTTP headers. Since this method is trying to write
"x-protobuf" headers after that, protobuf support wasn't working
properly for the default "x-protobuf" media type.
Thanks Toshiaki Maki for the repro project!
Also fixed:
* improve `MockHttpOutputMessage` behavior to reproduce the read-only
state of HTTP headers once they've been written.

Update PathMatchingResourcePatternResolver to include additional
protected methods that can be used by subclasses to optimize which
JARs are searched.
Issue: SPR-12231
Update SystemEnvironmentPropertySource to attempt optimized Map lookups
first, and only fall-back to the defensive SecurityManager safe-mode
if these fail.

This change defers determination of whether to invoke a message
converter in case of a null @ResponseBody value (or ResponseEntity with
a null body) until after the invocation of the ResponseBodyAdvice
chain. This allows a ResponseBodyAdvice to handle null values
potentially turning them into non-null value.s

This change extends the "websocket" scope to ApplicationContext events
published from StompSubProtocolHandler. This however will only work
with ApplicationEventMulticaster that multicasts events in the same
thread.

Refine property source ordering so that sources already contained in the
environment remain before those added by @PropertySource annotations.
Issue: SPR-12198
Update JndiLocatorDelegate.isDefaultJndiEnvironmentAvailable() to
call `getEnvironment()` on the `InitialContext` in order to actually
trigger a NamingException if JNDI is not available.
Issue: SPR-12223
Update ConditionEvaluator to collect then sort Conditions before
evaluation. By annotating Conditions with @Ordered expensive operations
can be pushed to the back of the queue.
