Classes come out empty

[KTibow]

I was trying to deobfuscate/decompile a mod obfuscated with Branchlock, but all the classes are pretty much empty. For example, here's the original file:

    package SBToolkit.utils;

import java.lang.management.ManagementFactory;

Hi!
Hmm I have to say that your source code is a bit... interesting I would say but yea it should be able to work with it without a problem... I will try to fix this in some future releases, it looks like to be some sort of problem with static initialization block.
But until then only thing you can do is predecompile it with external decompiler such as http://www.javadecompilers.com/
and deobfuscate the decompiled version afterwards. Just like it used to be before 1.2.0...

I know, it's a rat lol

Anyway thanks for letting me know, I'm not that interested in continuing work on deobfuscating it right now, but hopefully this helps someone else. Closing for now.
