/**

 * Test case for CalendarNameProvider.

 *

 * Test strategy:

 * com.bar.CalendarNameProviderImpl supports only ja_JP_kids locale. It returns

 * month names only in full-width digits, followed by "gatsu" in Hiragana if

 * it's a long style. The standalone styles are used because DateFormatSymbols

 * has precedence for the format styles.

 *

 * Calendar.getDisplayName(s) should be called with kids to get the month

 * names provided by com.bar.CalendarNameProviderImpl. Other display names

 * should be the same as what a Calendar constructed with ja_JP returns.
