[jira] [Created] (QPID-6171) [Java Common] Connection.getChannels() leaks a potentially thread-unsafe data structure

             Summary: [Java Common] Connection.getChannels() leaks a potentially thread-unsafe data structure
                 Key: QPID-6171
                 URL: https://issues.apache.org/jira/browse/QPID-6171
             Project: Qpid
          Issue Type: Bug
          Components: Java Common
            Reporter: Rob Godfrey
            Assignee: Rob Godfrey
             Fix For: 0.31


the collection returned by getChannels() may be modified by other threads, leading to unsafe iteration throwing ConcurrentModificationException.

The returned object should instead be a copy of the data and the underlying map should use a thread safe implementation to allow for the safe copying of the values() collection while another thread may be modifying the map.
