Java client should throw a protocol violation exception if it receives frames intended for a session that is already detached.

                 Key: QPID-2176
                 URL: https://issues.apache.org/jira/browse/QPID-2176
             Project: Qpid
          Issue Type: Bug
          Components: Java Client
    Affects Versions: 0.5
            Reporter: Rajith Attapattu
            Assignee: Rajith Attapattu
             Fix For: 0.6


The JMS client is currently vulnerable if a peer sends frames for a session that is already detached.
The JMS client will throw a NPE as it will try to invoke the commands on  a null reference.
The client needs to check if the session is detached and if so should a protocol violation exception.

Rajith Attapattu resolved QPID-2176.
------------------------------------

    Resolution: Fixed

I added a fix at rev 832441 in Qpid trunk to throw a ProtocolViolationException if a method is received on an already detached session.
Rob had already added the null check in rev 829675 in Qpid trunk to avoid calling the method on a null session.
