SpawnTP.

SpawnTP is an exploit that teleports a player to the server's spawn point without losing health. Fixed as of 2Beta2T.

There are various implementations of this exploit, but the basic one is simply sending the appropriate packet to the server, causing it to teleport the player to zero coordinates, i.e., the spawn point.

The simplest implementation of the exploit:

mc.getSendQueue().addToSendQueue(new Packet11PlayerPosition(Double.NaN, Double.NaN, Double.NaN, Double.NaN, true));


It is used, among other things, in the Rose cheat client.
