  ****************************************************************
  1. If a DataMover is started and its last recorded checkpoint
     is no longer present in the log stream it enters a loop
     of message DRLJ0179E.
  
  2. The Hub DataMover can fail with an
     ArrayIndexOutOfBounds exception shortly after making contact
     with one or more Spoke DataMovers when a configuration with
     multiple TCPIP output stages is used.
  

Problem conclusion

• 1. The DataMover is modified to terminate cleanly if a
     checkpoint location cannot be found in the input logstream.
  
  2. The DataMover has been enhanced so that it can manage
     multiple TCPIP output stages.
