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.
