APAR Error Description / Circumvention

-----------------------------------------------
Forced termination of a job running Java (for ENDJOB, ENDSBS,
etc.) may hang because of deadlock between the MI initial thread
that is/remains attached to PASE while waiting for all MI
secondary threads to end, and an MI secondary thread that waits
for all threads to detach from PASE.  ENDJOBABN is required to
end the job after deadlock occurs.

This condition has only been observed in jobs that start PASE in
an MI secondary thread and (later) attach to PASE in the MI
initial thread, so it may be an issue only for jobs that run the
J9 JVM.

CORRECTION FOR APAR MA45559 :
-----------------------------
Termination cleanup for PASE is changed to avoid waiting for
other threads to detach if the job is ending.

CIRCUMVENTION FOR APAR MA45559 :
--------------------------------
None.
