使用ASM重命名类会在编译的jar上抛出ClassCastException和AbstractMethodError

Question

我正在尝试使用ASM ClassRemapper将所有类从已编译的.jar重命名为新名称几乎一切正常，我的应用程序正常运行，直到它与ClassCastException或AbstractMethodError崩溃

ClassRemapper adapter = new ClassRemapper(classWriter, new Remapper()
{
    @Override
    public String mapType(String s)
    {
        return super.mapType(getNewName(s));
    }

    @Override
    public String mapFieldName(String owner, String name, String descriptor)
    {
        Type type = Type.getType(descriptor);
        descriptor = descriptor.replace(type.getClassName(), getNewName(type.getClassName()));

        return super.mapFieldName(getNewName(owner), name, descriptor);
    }

    @Override
    public String map(String internalName)
    {
        return getNewName(internalName);
    }

    @Override
    public String mapDesc(String descriptor)
    {
        Type type = Type.getType(descriptor);
        descriptor = descriptor.replace(type.getClassName(), getNewName(type.getClassName()));

        return super.mapDesc(descriptor);
    }

    @Override
    public String mapMethodDesc(String methodDescriptor)
    {
        Type methodType = Type.getMethodType(methodDescriptor);

        List<Type> types = new LinkedList<>();

        for (Type argumentType : methodType.getArgumentTypes())
            types.add(Type.getType(argumentType.getDescriptor().replace(argumentType.getClassName(), getNewName(argumentType.getClassName()))));

        Type returnType = Type.getReturnType(methodDescriptor);
        returnType = Type.getReturnType("()" + returnType.getDescriptor().replace(returnType.getClassName(), getNewName(returnType.getClassName())));

        return super.mapMethodDesc(Type.getMethodDescriptor(returnType, types.toArray(new Type[0])));
    }
});

我想我在方法中缺少一些东西，但我找不到什么。

getNewName(string)基本上是map.getOrDefault(string, string);
