I agree with this. If I read the code correctly the exception stack trace will be logged only if there are active stream, and in our case, the timeout should fire only when the connection is idle - so it should have no active stream. If it's being closed when there is an active stream then this is an error and we want to see it as such. The current code, as proposed here, does that.
