Your decompiler, bro. Mine gave me "jsonarray" in lower cases. Nonethless, if u can't recompile decompiled source back into working program, u can try to do 2 things: correct misreadings (if u don't have any experience with Java, u can use Google or precompiled source of 0.4.7e) or post any obfuscated parts u found to our review.

Ofc, if u're not just trolling.
