Key: CAMEL-7950

Project: Camel
Issue Type: Improvement
Reporter: Aaron Whiteside
SJMS's Producers creates a new Session per message request, this is both a
performance issue and a problem when using transactions.
Sessions should be cached in ThreadLocal for performance reasons. Of course you
may want to limit the total number of cached sessions or even implement a
stack/queue of sessions to reuse. As long as a new session isn't create for
every single message produced to a Queue/Topic.
Second the same session should be used for any consumption and production to
any queues by a thread when transactions are enabled. If a single route is
consuming from JMS and producing to JMS, one would expect the same session to
be used to provide atomic consumption and production to the queues/topics
involved.
