Typo in ThreadPoolExecutor.afterExecute()

    Description

      A DESCRIPTION OF THE PROBLEM :
      The code in the javadocs mentions

           r instanceof Future<?>
      and
           result = ((Future<?>) r).get()

      The Future there should be changed to FutureTask. r is a Runnable and Future doesn't implement Runnable but FutureTask does and is mentioned in the javadocs about the code.


      EXPECTED VERSUS ACTUAL BEHAVIOR :
      EXPECTED -
           r instanceof FutureTask<?>
      and
          result = ((FutureTask<?>) r).get()
      ACTUAL -
           r instanceof Future<?>
      and
           result = ((Future<?>) r).get()
