  Access to the queue that holds the asynchronous internal
  loggers needs to be synchronized to handle timing conditions
  where the queue might be emptied by the time another
  asynchronous logger gets queued.
  This is most likely to be seen with FFDC loggers as these
  loggers are configured to be asynchronous.  The
  NullPointerException will occur when WsLogger.queueAsyncEvent
  gets invoked.
  

Problem conclusion

• Access to the queue that holds the asynchronous internal
  loggers has been synchronized to handle timing conditions
  where the queue might be emptied by the time another
  asynchronous logger gets queued.
  
  The fix for this APAR is currently targeted for inclusion in
  fix pack 7.0.0.31.  Please refer to the Recommended Updates
