      The bug

      The new Minecraft command parser does not check for int-overflows in command arguments. This causes the game to instantly freeze as soon as the command is executed.

      How to reproduce

      1. Execute the command /tp ~ 9223372036854775807 ~
      2. Notice that the game freezes
      3. Trying to rejoin the world instantly kicks the player with the message "Invalid move player packet received".
