    Description

      When the RA's connection to the broker fails and the <i>ActiveMQManagedConnection.onException()</i> method is called, all the registered <i>ConnectionEventListener</i>s are notified.
      At least in Glassfish, the registered listener then calls the <i>ActiveMQManagedConnection.removeConnectionEventListener()</i> to unregister itself. This causes a <i>java.util.ConcurrentModificationException</i> to be thrown since the <i>ConnectionEventListener</i> collection is modified while the <i>onException()</i> iterates over it.
