"Unable to open file" due to method signature ClassCastException #276

Closed queer closed 3 years ago

queer commented 3 years ago

I ran into this when decompiling Minecraft 1.16.5, aqm.class.

Stacktrace 

java.lang.ClassCastException: class com.strobel.assembler.metadata.CoreMetadataFactory$MethodSignature cannot be cast to class com.strobel.assembler.metadata.MethodReference (com.strobel.assembler.metadata.CoreMetadataFactory$MethodSignature and com.strobel.assembler.metadata.MethodReference are in unnamed module of loader 'app')

Sorry; this is actually an issue upstream with procyon, and I've filed an issue https://github.com/mstrobel/procyon/issues/16
