Class SyntheticParameterClassVisitor

java.lang.Object
org.objectweb.asm.ClassVisitor
net.fabricmc.loom.util.SyntheticParameterClassVisitor
public class SyntheticParameterClassVisitor extends org.objectweb.asm.ClassVisitor
ProGuard has a bug where parameter annotations are applied incorrectly in the presence of synthetic arguments. This causes javac to balk when trying to load affected classes.

We use several heuristics to guess what the synthetic arguments may be for a particular constructor. We then check if the constructor matches our guess, and if so, offset all parameter annotations.
