Currency.getDisplayName(new Locale(“ru”, “RU”) выводит “Russian Ruble”. Так и задумано?

    Currency cur = Currency.getInstance(Locale.forLanguageTag("ru-RU"));
    System.out.println(cur.getSymbol());
    System.out.println(cur.getDisplayName(new Locale("ru", "RU")));
    System.out.println(cur.getDisplayName());

Output:

руб.
Russian Ruble
Russian Ruble

API говорит:

Gets the name that is suitable for displaying this currency for the specified locale. If there is no suitable display name found for the specified locale, the ISO 4217 currency code is returned.

Я где-то ошибаюсь, или такова поддержка русской локали в Java SE8 ?
