-Subject: [PATCH] handle ServerboundKeepAlivePacket async
-
-In 1.12.2, Mojang moved the processing of ServerboundKeepAlivePacket off the main
-thread, while entirely correct for the server, this causes issues with
-plugins which are expecting the PlayerQuitEvent on the main thread.
-
-In order to counteract some bad behavior, we will post handling of the
-disconnection to the main thread, but leave the actual processing of the packet
-off the main thread.
-
-also adding some additional logging in order to help work out what is causing
-random disconnections for clients.
