Hello. I'm using javassist 3.1, and I want to add parameters to an existing method. I haven't found anything in the API that supports that, so I've tried to create a new method with the new parameters, and copy the method body over from the old method to the new (by copying over the CodeAttribute). But when I try to instrument the new method using ExprEditor.edit(NewExpr e) (I want to add a code line after a "new" statement), the "$args" identifier references the NewExpr parameters rather than the method parameters. This makes me think that the copying ov the method body wasn't done correctly. Does anyone have a clue?
