I'm having this same issue on my server. Can't understand it. I'm using FTB Beta A, not sure about this guy.

alright so i figured it out my problem was that when i wanted to enable cave map and entities on rei's minimap i downloaded the wrong file for the loginmessage mod, i downloaded the vanilla version when i should have downloaded the forge compatible version. Hope this helps =]

Im having the same error and tried switching to the Forge compatible version of the Loginmessage file but the error persists, can you tell me which versions of the mods your using ? (rei's/twilight) because this error is greatly annoying
