I fail to understand this; I have not tested STS extensively.
Is it not the case that an inner scope will be cancelled when its
parent scope is cancelled?
The forked subtask would be joining the inner scope; will this inner
join not be cancelled when the outer join is cancelled?
In what sense does an inner scope not participate in the same error
handling as the outer scope?
When the outer/parent scope is cancelled then all threads executing
unfinished subtasks will be interrupted. If a subtask has created it own
scope and invokes join to block waiting for its sub-subtasks, then it
will wakeup with InterruptedException, and the exception handling will
cause its scope to be closed, thus interrupting any remaining
sub-subtasks. So yes, cancelling the parent scope may result in a "tree
of scopes" being cancelled.
