Thomas Wolf commented on SSHD-1290:
-----------------------------------
Probably not "racy"; I don't see unsynchronized accesses in the code. Not sure
what might be going on; might be just a symptom of an immediate channel closure
(perhaps after other errors) while a write was still being attempted. In that
case I would expect the {{writeState.pendingFuture}} to be {{{}null{}}}, and
the log entry might be harmless. Can you determine from other log entries if
that might be the case? Otherwise we should probably log a bit more, or
differently if it's really that case.
Does the log contain any line number? That would be helpful, too.
