bug APIs cause freezes

[crazytobuildmc]

This is a major problem I am having with my own private non-launcher modpack.

Whenever my Forge tries to PreInitialise any 'API' (McJtyLib, iChunUtil, CoFHCore - only tested on these) it stops working and the Game Output throws up a debug crash.

This is really bugging me, so how can I stop this? I contacted McJty for help, and he has no clue. He has advised me to ask on a modding forum, and this is the forum I chose.

Edit: Link to an output here, from 1.7.10 (it also happens on 1.8):

Looks like I'll never get an answer...
