More information:  

If I add this debug statement to PlayRecord.java, it prints NULL after the 
recorder.deactive();

  private void terminateRecordPhase() {
        if (recorder != null) {            
            recorder.deactivate();

            logger.error("recorder state? (" + recorder +")");

            recorder.removeListener(recordingHandler);
            recorder=null;
        }

moving the recorder.removeListener(recordingHandler) above 
recorder.deactivate() either masks the problem or makes it go away.

Thats normal behaviour since you send Rqnt with ES and right away delete all 
endpoint connections with DLCX.
Since dlcx is executed faster then RQNT you end up fighting on who will release 
the resources.
Bottom line : there is no need to send es before dlcx , or you should wait for 
answer before sending DLCX.
