APAR status

• Closed as program error.

Error description

• Situation: Customer has nested Asynchronous method calls where
  asynchronous method A calls B which calls C. A -> B -> C. A
  and B then
  call Future.get(timeout,unit).
  
  If C hangs, B's Future.get(timeout,unit) will not honor the
  timeout and will be stuck. The timeout is only honored in A,
  which will eventually throw a TimeoutException. Method B never
  completes.
  
  After this fix, the timeout in B is honored and will throw the
  TimeoutException, and then continue as long as the timeout in
  A is greater than the timeout in B.
