> The implementation of JMS Session uses a thread to dispatch messages to 
> message listeners. This thread is created on instantiation of the Session 
> even though it is only required if the application goes on to create a 
> MessageConsumer with a MessageListener from the Session. For environments 
> that create lots of Sessions with only MessageProducers then this is an 
> unnecessary overhead. The recommendation is to change the Session 
> implementation to only create these dispatcher threads when required.
