In 1.12.2, Mojang moved the processing of PacketPlayInKeepAlive 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 on the main thread.

Subject: [PATCH] handle PacketPlayInKeepAlive async
|
|
|
|
In 1.12.2, Mojang moved the processing of PacketPlayInKeepAlive 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
|
|
on the main thread.
