The bug
Occasionally, when interacting with multiplayer servers (probably on the server list, but I'm not completely sure), the following error is logged in the game log.
[Netty Client IO #1/WARN]: An exceptionCaught() event was fired, and it reached at the tail of the pipeline. It usually means the last handler in the pipeline did not handle the exception. java.nio.channels.ClosedChannelException: null at io.netty.channel.AbstractChannel$AbstractUnsafe.write(...)(Unknown Source) ~[netty-all-4.1.25.Final.jar:4.1.25.Final] [Netty Client IO #2/WARN]: An exceptionCaught() event was fired, and it reached at the tail of the pipeline.

I'm unsure of the significance of this issue, but I have experienced the issue multiple times within the past few days and it didn't seem to have an impact on the game.
