            Root<Customer> customer = cquery.from(Customer.class);
            EntityType<Customer> Customer_ = customer.getModel();
            EmbeddableType<Country> Country_ = mm.embeddable(Country.class);

            cquery.select(customer.get(Customer_.getSingularAttribute("country", Country.class)).get(Country_.getSingularAttribute("code", String.class)));

            List<Expression<?>> groupList = cquery.getGroupList();
            if (groupList == null) {          
                System.out.println("getGroupList returned null instead of empty list when no groupby expressions have been specified");
