Because this exploit has been widely known for years and has not been fixed by Mojang, we decided that it was worth allowing people to toggle it on/off due to how easy it is to make it configurable. It should be noted that this decision does not promise all future exploits will be configurable.

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)
