    Thanks! (Using 1.6.2)

    IC2e need some special form of "broken API" detection:

    1) on mod parseinit (real preloading stage, moment when forge assembled list, checked integrity of classes but not yet inited any mod) engine shoud read some field from class inside API, if field not available or contain invalid data - shoud check classloader data, md5 or CRC of class will also do job but just reading field better.

    2) classloader keep info about source of class, this data can be used to detect source of class.

    with this knowlage IC2e can output:
    mod A incompatable with IC2e remove\update it of GTFO

    i can compile sample mod if anyone interested.
