Subject: [PATCH] Fix player kick on shutdown
Fix preemptive player kick on a server shutdown.
If you update minecraft version / upstream and something is changed in this method make sure that a server doesn't disconnect a player preemptively,
also check if all packets are ignored during the shutdown process.
See net.minecraft.network.Connection#channelRead0(ChannelHandlerContext, Packet) and net.minecraft.util.thread.BlockableEventLoop#executeIfPossible(Runnable)
