Unobfuscation is not possible. #891

I did detect first because I do not know what obfuscator is.

SourceFileClassNormalizer and output the file, the software will not start. What should I do? I think my deobfuscation mesosot is wrong because I get a java.lang.ClassFormatError: incompatible magic value error and cannot start the software.

The SourceFileClassNormalizer is not doing deobfuscation. It just renames classes to what their SourceFile attribute says they were named.

If, and only if, you can legally share the input jar (see #653 ) (or provide a link to it where it was shared by its creator for the general public), I or others could take a look at it - maybe it is not actually obfuscated, maybe its obfuscated with an unsupported obfuscator, maybe one detection algorithm didn't work like it should.

Thank you for your answer. Unfortunately it is a protected file and I will give up after reading the rules.
