Hi,
One experience using Structured Concurrency:
When there is a timeout, even the succeded subtasks throws illegal
state exception, I guess due to the fact that owner is not joined.
The join method can't throw TimeoutException and return a result at the
same time. Also the SO post is using ShutdownOnFailure but doesn't want
to shutdown when a subtask fails.
For the example then using STS directly and having a subtask shutdown
the scope should work, e.g.
scope.fork(() -> {
Thread.sleep(2000);
scope.shutdown();
return null;
});
So no joinUntil or TimeoutException to deal with.
The topic of "give me what you got" before some deadline or timeout
would be a bit easier in the upgraded API with a Joiner factory method.
We need to see if this case is common enough to justify that.
