So what causes this?

I am relatively sure, CFR is causing this issue and we can't do much about it. Which class/jar file are you trying to decompile?

If you don't hold the appropriate legal rights of that file, don't upload it!!! Please send us a link to the file.

I'm trying to decompile a dex file, sorry i haven’t the linke to the file

Miscf commented 3 years ago

In fact, both CFR and Procyon failed.

ThexXTURBOXx commented 3 years ago

Okay, no problem. There are some problems with dex files atm. We will try to investigate the issue when we find some failing DEX/APK.
