Problem summary

• ****************************************************************
  * USERS AFFECTED:  All users of IBM WebSphere Application      *
  *                  Server Liberty Profile                      *
  ****************************************************************
  * PROBLEM DESCRIPTION: Asynchronous activities may be woken    *
  *                      early by the JVM and incorrectly        *
  *                      timed out causing FFDCs.                *

  * RECOMMENDATION:                                              *
  ****************************************************************
  The presence of both
  java.util.concurrent.TimeoutException at
  com.ibm.ws.threading.internal.NonCancelableResultFuture.get(NonC
  ancelableResultFuture.java:65)
  and,
  java.lang.InterruptedException at
  com.ibm.ws.threading.internal.NonCancelableResultFuture.get(NonC
  ancelableResultFuture.java:50)
  indicate that the waiting NonCancelableResultFuture was
  awoken early by the JVM. This may be followed by various other
  errors in cases where follow on code is affected by the
  NonCancelableResultFuture timing out instead of reporting as
  done.
  

Problem conclusion

• After the NonCancelableResultFuture is notified a check of the
  elapsed time waited is made and if the timeout has not really
  passed the NonCancelableResultFuture waits again.
  
  
  
  The fix for this APAR is currently targeted for inclusion in
  fix pack 8.5.0.1. Please refer to the Recommended Updates page
