Lambdas do not get remapped

[TwilightFlower]

When remapping a lambda, everything appears to get remapped properly except the name of the method to implement. (The invokedName parameter of LambdaMetafactory.metafactory.) This results in an AbstractMethodError when the lambda is called.

Presumably this issue is meant for Lorenz? (don't close, I can move it)

Though could you supply some example mappings that are causing issues?

Ah, sorry for putting this on the wrong project. Specifically, I was remapping Minecraft Forge universal (everything under the net.minecraftforge package) from SRG to obfuscated. I don't remember exactly where the error cropped up, though -- I forgot to create this issue for a few weeks. I could create a smaller test case to demonstrate it when I have more time in a week or so.

Did you get chance to follow this up at all?

public interface TestLambda {
    static final TestLambda TEST = () -> System.out.println("test");
    void hello();
    
    public static void main(String... args) {
        TEST.hello();
    }
}

TestLambda TestLambda
	hello ()V goodbye

Exception in thread "main" java.lang.AbstractMethodError: TestLambda$$Lambda$1/754666084.goodbye()V
        at TestLambda.main(TestLambda.java:6)

Simple enough test case. It is borked.

This is my fix in SS for it, gunna hack it into my fork for the time being. LexManos/SpecialSource@ef5ac81
