StackOverflowError when LAN world is closed

The bug

If the host of a LAN world closes the world while other players are still playing on that world, those players will be kicked with a java.lang.StackOverflowError error message. The kick message should be something like "Server closed" instead.

To reproduce

1. Open a world to LAN
2. Join the LAN server using another account
3. Close the LAN world
4. The player that joined the LAN server will be kicked with the error message
