  ****************************************************************
  A Liberty JVM server that uses Link to Liberty is shutting down.
  The Link to Liberty listener task is posted by CICS to terminate
  the listener thread.
  Liberty then stops the Link to Liberty CICSResourceAdapter.
  The resource adapter also tries to terminate the listener
  thread.  This second attempt to terminate the listener results
  in an 0C4 abend in DFHSJWLI.

Problem conclusion

• CICS has been changed to not try to set the Link to Liberty
  listener inactive when it has already been terminated.
