  ****************************************************************
  In some cases, the clearClassCache script, when run on z/OS,
  will fail to successfully clear out some shared memory,
  producing a warning message.  The message is generally benign
  but can be alarming to users.
  

Problem conclusion

• The clearClassCache script was updated to suppress the warning
  messages, consistent with the behavior on previous Java
  releases.
  
  The fix for this APAR is currently targeted for inclusion in
  fix pack 8.0.0.3.  Please refer to the Recommended Updates
