The new UserDestinationMessageHandler resolves messages with
destinations prefixed with "/user/{username}" and resolves them into a
destination to which the user is currently subscribed by appending the
user session id.
For example a destination such as "/user/john/queue/trade-confirmation"
would resolve "/trade-confirmation/i9oqdfzo" assuming "i9oqdfzo" is the
user's session id.
Remove base class for STOMP-related message handler classes
(AbstractSimpMessageHandler), polish subclasses and fix issues with
more significant updates to STOMP broker relay.
Introduce base class for SubscribableChannel implementations providing
consistent logging for all channel implementations.
The SubscriptionRegistry and implementations are now in a package
together with SimpleBrokerWebMessageHandler and primarily support
with matching subscriptions to messages. Subscriptions can contain
patterns as supported by AntPathMatcher.
StopmWebSocketHandler no longer keeps track of subscriptions and simply
ignores messages without a subscription id, since it has no way of
knowing broker-specific destination semantics for patterns.
Add ByteBufferConverter that is registered by default with the
DefaultConversionService. Allows conversion from/to a ByteBuffer and
byte[] or to any type that can be converted via a byte[].

When headers are being removed based on pattern matching, both the
new header names and the original header names need to be matched
against the pattern. Previously, only new headers were being
considered resulting in any matching original headers not being
removed.
When a header is being set, verify that the type that's provided is
legal for the header that's been set. For example, the error channel's
type must be a MessageChannel or a String.
The method that performs type verification is protected so that it
can be overriden by sub-classes. It is expected that an overriding
method will call the super method.
Update the cached MethodExecutor in MethodReference to include the
target type. Prevents the incorrect use of the cache when the
SpEL expression refers to a different target object.

The Reactor Environment (that's used by the TcpClient) manages a
number of threads. To ensure that these threads are cleaned up
Environment.shutdown() must be called when the Environment is no
longer needed.
Ensure any exception from calls to batchUpdate, on databases that
support batch operations, contains all the SQL statements. Prior to this
commit only the last SQL statement would be returned with the exception.
