Given you have the following classes:

interface GenericInterface<T> {
   default List<T> returnGenericList() {
      return List.of();
   }
}

// Note: T isn't the same as in GenericInterface
interface Service<T> extends GenericInterface<String> {
   class Impl implements Service<Long> {

   }
}

Resolve the generic return type of Impl.returnGenericList via reflection.

Expected result: java.util.List<String>
