> Sometimes async write listener is not called
> --------------------------------------------

> Key: SSHD-1261
> URL: https://issues.apache.org/jira/browse/SSHD-1261
> Project: MINA SSHD
> Issue Type: Bug
> Affects Versions: 2.8.0
> Reporter: Evgeny Pasynkov
> Assignee: Lyor Goldstein
> Priority: Major

> Hello,
> I have discovered the case when the async write listener is not called.
> Imagine the case: The `ChannelAsyncOutputStream::doWriteIfPossible` method
> discover that window size is too small (lines 160-167). It setup new future
> and exit the doWriteIfPossible method, relying on `onWindowExpanded` will be
> called shortly. But if the channel is disconnected, the method will never be
> invoked, thus future won't be completed.
> I suggest adding the following override to ChannelAsyncOutputStream class:
> {code:java}
> @Override
> protected void doCloseImmediately() {
> abortCurrentWrite();
> super.doCloseImmediately();
> }
> protected synchronized void abortCurrentWrite() {
> IoWriteFutureImpl future = pendingWrite.get();
> if (future != null) {
> future.setValue(new ClosedChannelException());
> }
> }
> {code}
