Woah, very good to know. And thus, even when the scope is closed,
onFork will still be called is what you are saying?
Thanks for this. Very useful.
No, fork is specified to throw IllegalStateException if closed. My
comment is pointing out that if you cancel the scope then the result
from any subtasks that are still executing does not contribute to the
outcome. Once you cancel then onComplete for these "still running (and
interrupted)" subtasks won't be called. To put it another way, if the
outcome from join is something derived from all subtasks that were
forked then you'll need to implement onFork. It may be more common that
the outcome is derived from the result/exception from a subset of the
subtasks, in which case it will be the onComplete method that you implement.
