Updating netty manually for Minecraft 1.12

Get your minecraft_server.1.12.2.jar from the root of your server, download the latest netty full package http://dl.bintray.com/netty/downloads/netty-4.1.37.Final.tar.bz2

Open your server jar with 7zip and navigate to minecraft_server.1.12.2.jar\io\netty\

open the netty package you downloaded and go to netty-4.1.37.Final.tar.bz2\netty-4.1.37.Final.tar\netty-4.1.37.Final\jar\all-in-one\netty-all-4.1.37.Final.jar\io\netty\

back in the minecraft server jar delete these 6 folders

now simple copy the same 6 folders from the netty package into the minecraft jar

throw the jar back into the root of your server and you are done!
