ActiveMQ client ResponseCorrelator doesn't handle ExceptionResponse commands correctly.
---------------------------------------------------------------------------------------

                 Key: AMQNET-360
                 URL: https://issues.apache.org/jira/browse/AMQNET-360
             Project: ActiveMQ .Net
          Issue Type: Bug
          Components: ActiveMQ
    Affects Versions: 1.5.2, 1.5.1, 1.5.0
            Reporter: Timothy Bish
            Assignee: Timothy Bish
            Priority: Minor
             Fix For: 1.6.0


The current implementation of the ResponseCorrelator deals with exception responses by calling
the transport exception listener as well as throwing an exception from the request methods
instead of just returning the ExceptionResponse message and allowing the caller to deal with
the error.  This prevents the caller from being able to recover from non-critical messages
as the ExceptionListener calls marks the transport as failed in the Connection when it needn't
be.  The correct operation should be for the ExceptionResponse to be propagated to the caller
(Connection) and allow that to deal with the error.

This is needed so that cases like TransactionRollbackException's returned from Commit requests
when a failover occurs and the State Tracker rolls back the transaction because its state
is in doubt.  This is not a critical error and the Connection should be allowed to continue
after this.  Other cases similar to this also exist.
