[Java 0-8 Client] Failover during transaction may cause erroneous attempts to
acknowledge in new connection
-----------------------------------------------------------------------------------------------------------
Key: QPID-2745
URL: https://issues.apache.org/jira/browse/QPID-2745
Project: Qpid
Issue Type: Bug
Components: Java Client
Affects Versions: 0.6
Reporter: Rob Godfrey
It was observed that a failover (in the case caused by a timeout) caused the
client to attempt to ack messages on the new connection that has been received
on the old connection - this caused a broker error:
2010-06-25 14:04:28,766 ERROR [pool-2-thread-14]
protocol.AMQMinaProtocolSession (AMQMinaProtocolSession.java:409) - Unexpected
exception while processing frame. Closing connection.
