Hum nice catch..it will works when the remotlyClosed is invoked, but right now it will not work when the locallyClosed is invoked. The reason is I wanted to make sure the SelectionKey and its associated Channel are closed before invoking the handler.
Let me rework the implementation to make sure I support your use case.
Thanks for the feedback.
