             Summary: potential NPE in transport while establishing SSL connection
                 Key: QPIDJMS-146
                 URL: https://issues.apache.org/jira/browse/QPIDJMS-146
             Project: Qpid JMS
          Issue Type: Bug
          Components: qpid-jms-client
    Affects Versions: 0.7.0
            Reporter: Robbie Gemmell
            Assignee: Robbie Gemmell
             Fix For: 0.8.0


There is an issue in the SSL transport, such that it can potentially NPE while establishing the connection, resulting in the attempt hanging.

The issue looks to occur due to the way we are adding a listener to Netty, hitting some inconsistency in thread safety, coupled with unpredictable threading behaviour at the point the listener is added to a future versus it being completed, topped by Netty swallowing the exception when it is thrown.

We should adjust the usage of Netty so that we register the listener earlier such that it gives more predictable thead behaviour and avoids possibility of the NPE.
