Hi Brad, I've tried Procyon, Jad, and CFR. The results are in WINDUP-50 and subtasks. I wanted to ask - Jad tells me it doesn't support .class v50 even if I run JadRetro before. Also, this only happens for just 25 classes out of 1200. Seems like the JadRetro failed to transform or such. Have you also observed this? Any tip how to improve? Thanks, Ondra
