Hiram R. Chirino 2984963912 If you have a multi-threaded client which share 1 connection to the broker it is possible you may have seen errors like:

root cause is that the client side has multiple threads calling close() on consumer/session and the connection objects. If the timing of those concurrent calls was just right, it is possible for the client to send the connection close message followed by a session or consumer close message which is invalid and would result in IllegalStateException reported by the broker.

- Simplified the ActiveMQConnection and TransportConnection shutdown so that this does does not happen.
