调研方向
The reporter traces the bug to the kick handling in paper-server/patches/sources/net/minecraft/server/network/ServerGamePacketListenerImpl.java.patch, where a null leave message falls back to the default. Read the PlayerList#remove overloads and how PlayerQuitEvent supplies the final message, then reproduce with a plugin that calls leaveMessage(null) on PlayerKickEvent. Done means a null leave message suppresses the broadcast without breaking the quit event.

描述
Expected behavior
If I call PlayerKickEvent.leaveMessage(null), the leave message is set to null and so not sent, like it says in the description of the method.
Observed/Actual behavior
The leave message is still sent.
Steps/models to reproduce
@EventHandler
private void onPlayerKick(PlayerKickEvent event) {
event.leaveMessage(null);
}
- Log in with 2 accounts
- Kick one of them
- Observe leave message still being present
Plugin and Datapack List
Replicated with only my plugin.

Other
During my own analysis with the debugger and browing through source in intellij I came to the conclusion that it is caused by this line, which if the leave message is null, PlayerList#remove(net.minecraft.server.level.ServerPlayer) instead uses the default leave message. Then in PlayerList#remove(net.minecraft.server.level.ServerPlayer, net.kyori.adventure.text.Component) it calls PlayerQuitEvent with the supplied leave message, and uses the leave message out of that event, so using that event still works, but it's called later and doesn't have all the context.
