Hi, I'm stumbling over the behaviour of OutputStreamSubscriber as instantiated by StreamConverters.fromOutputStream: In the case that my stream fails, I need to clean up after my operations, but the cleanup depends on the stream being closed first.
But OutputStreamSubscriber completes the underlying promise instantly with a "Failure" IOResult if it receives errors from up- or downstream, and then tries to complete the promise again in postStop(). This means that (a) I can't wait for the stream to be closed as postStop is async and (b) I get an exception from postStop for the "error during closing stream" case since the promise is already completed. (1) What's the correct pattern to make sure the OutputStream is closed? Should I keep an outside reference to it and manually close it? Or can I somehow wait for postStop()? (2) Is the second, irregular completion of the promise in OutputStreamSubscriber intended behaviour? Why does the exceptional case in postStop() not trySuccess() rather than success()?
