2004-07-09  Bryce McKinlay  <mckinlay@redhat.com>

	* java.util.Calendar.java (cache): New private static field. Cached
	mappings of locales->calendar classes.
	(ctorArgTypes): New private static field. Singleton argument for
	calendar class constructor lookup.
	(getInstance): Cache Locale->Calendar class mappings using HashMap.
	Optimize by bypassing reflection instantiation for the
	GregorianCalendar case.
