Since when is the minecraft_server.jar downloaded from minecraft.net a 'modded version of minecraft'? This is 100% vanilla, done with no mods, default texture pack in the client, and a brand new world.
There is no way to get more vanilla than this.
Confirmed on 1.4.6 vanilla and craftbukkit. Crashes server every time.
Crash log attached.
