Hi Doug,

In Future::exceptionNow() and Future::state() I would think we would want to catch CancellationException since the implementation of the Future is not known.  Even though we pre-screen the state I would imagine there could be an implementation that prefers cancellation over normal completion.

For Future::resultNow() and FutureTask::resultNow(), is it intentional that we are not chaining just ExecutionException::getCause() / (Throwable) outcome as the cause of the IllegalStateException?  Chaining that might help with debugging even if that is not how it is suppose to be used.

Jason
