`exceptionNow` is specified to call `get`, which does not throw
`CompletionException`:
* @implSpec
* The default implementation invokes {@code isDone()} to test if the task
* has completed. If done and not cancelled, it invokes {@code get()} and
* catches the {@code ExecutionException} to obtain the exception.
