[Fixes #1656] Lombok would silently do the wrong thing when using references to public static final String fields, instead of actual string literals, there where you can specify strings in lombok annotation parameters, such as @ToString(of = MyClass.CONSTANT_FIELD). We can’t really fix it, but at least now lombok will error when you do that and describe in detail what’s going wrong.
