    *                      ScheduledExecutorService interface      *
    *                      incorrectly processes TimeUnits not     *
    *                      specified in milliseconds               *

    * RECOMMENDATION:                                              *
    ****************************************************************
    Internal components schedule tasks for execution using internal
    implementations of the
    java.util.concurrent.ScheduledExecutorService interface.  If
    the TimeUnit specified on the schedule method was not
    TimeUnit.MILLISECONDS then the method performed an incorrect
    conversion resulting in tasks being executed after an
    incorrect delay, typically of a much shorter duration than
    expected.  Internal use of the internal implementation always
    specifies the TimeUnit in milliseconds, but product extensions
    that make use of the class could have been impacted.
    

Problem conclusion

  • The AlarmManagerCSLM.AbstractScheduledExecutorService class
    was modified so that the TimeUnit conversion was performed
    correctly.
    
    The fix for this APAR is currently targeted for inclusion in
    fix packs 8.5.5.12 and 9.0.0.3.  Please refer to the
