Related: - 27a25e29f7c002eb9f4d52b52ecccb2f3a7d6b15 Motivation: The commit mentioned above introduced a regression where channelReadComplete() event is swallowed by a handler which was added dynamically. Modifications: Do not suppress channelReadComplete() if the current handler's channelRead() method was not invoked at all, so that a just-added handler does not suppress channelReadComplete(). Result: Regression is gone, and channelReadComplete() is invoked when necessary.
