> A client uses failover to allow their client to reconnect to a second broker in the event
of failure of the primary. 
> There is a defect in the Qpid Java client's failover code that means if an attempted
reconnection fails 'late' in the connection start process, then the AMQConnection _closed
flag get set permanently to true and this prevents all future use of the AMQConnection object,
even after a successful reconnection.  By 'late' I mean a failure after the TCP/IP connection
has been successfully established - such as an authentication or authorisation problem that
causes the Broker to decide to close the connection.
> The problem affects both 0-10 and 0-8..0-9-1 code paths.
