> BroadcastChannel.asPublisher() fails a subscriber that arrives after the
> broadcast closed
> -----------------------------------------------------------------------------------------
>
> Key: GROOVY-12571
> URL: https://issues.apache.org/jira/browse/GROOVY-12571
> Project: Groovy
> Issue Type: Bug
> Components: async
> Affects Versions: 6.0.0
> Reporter: Scott Murphy Heiberg
> Priority: Major
>
> {code:groovy}
> import groovy.concurrent.BroadcastChannel
> def broadcast = BroadcastChannel.create()
> broadcast.close()
> for await (x in broadcast.asPublisher()) { println x } //
> ChannelClosedException; expected: ends without values
> {code}
> A subscriber that arrives after {{close()}} gets
> {{onError(ChannelClosedException)}}, and after {{close(failure)}} it gets the
> wrapper rather than the failure. A subscriber attached a moment before the
> close completes, or receives the failure itself, so the same program finishes
> or fails depending on timing. Expected: as {{SubmissionPublisher}},
> {{Agent.changes()}} and {{for await}} over a closed {{AsyncChannel}} behave,
> a late subscriber gets {{onComplete}} after {{close()}} and
> {{onError(failure)}} after {{close(failure)}}.
> {{BroadcastChannel.subscribe()}} still throws once closed.
> Behaviour change from 6.0.0: code that caught {{ChannelClosedException}} from
> a publisher of a closed broadcast now sees {{onComplete}} after {{close()}},
> or {{onError}} with the failure itself after {{close(failure)}}. The PR adds
> a COMPATIBILITY.md entry.
