Fuck java random

Psychic.java

        long oldSeed26 = ((long) old26 << (48 - 26)) & mask;
        long newSeed27 = ((long) new27 << (48 - 27)) & mask;

        // BruteForce the old seed
        for(long oldSeed = oldSeed26; oldSeed<=(oldSeed26|((1L << (48-26)))); oldSeed++){
            long newSeed = (oldSeed * multiplier + addend) & mask;
            if((newSeed & ((1L << 27) - 1) << (48 - 27)) == newSeed27){
                setSeed(newSeed^multiplier);
            }
        }
    }
}

More fucker solution is to modify Random class use reflect.
