             Summary: race during concurrent creation of initial connection
                 Key: QPIDJMS-498
                 URL: https://issues.apache.org/jira/browse/QPIDJMS-498
             Project: Qpid JMS
          Issue Type: Bug
          Components: qpid-jms-client
    Affects Versions: 0.50.0
            Reporter: Robbie Gemmell
            Assignee: Robbie Gemmell
             Fix For: 0.51.0


There is a race within some handling code for loading/creation of underlying client objects during creation of a connection which can occur during concurrent attempts to create the first connection after JVM startup, and could lead to failure for some of the attempts as they fail to provide required details.

It occurs due to accessing the related contents of some caching maps in the opposite order of their population and allowing a narrow window to violate expectation both details would be present. It cant occur again after the first connection creation has passed this point.
