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.
