      // This API was formerly @stable ICU 2.0
      static public ResourceBundle getDateFormatBundle(Class<? extends Calendar> calendarClass,
                                                       Locale locale)
          throws MissingResourceException {
          return null;
      }
docs: Finds the ResourceBundle containing the date format information for
  a specified calendar subclass in a given locale.
  <p>
  The resource bundle name is based on the calendar's fully-specified
  class name, with ".resources" inserted at the end of the package name
  (just before the class name) and "Symbols" appended to the end.
  For example, the bundle corresponding to "android.icu.util.HebrewCalendar"
  is "android.icu.impl.data.HebrewCalendarSymbols".
  <p>
  <b>Note:</b>Because of the structural changes in the ICU locale bundle,
  this API no longer works as described.  This method always returns null.
