> When calling flush on ChannelOutputStream, Window.waitForSpace may throw a WindowClosedException. This exception is always logged at error level, then rethrown. If Debug is enabled on the logger, the error log is issued twice (second time with stacktrace).
> During deinitialization it is common practice to call flush on output streams. Due to the asynchronous nature of the code in this library, the call may fail. The caller should decide how to deal with the exception and log at error level if needed.
> The implementation should not log at error level regardless.
> I would suggest INFO level instead (if logging at all).
