/**
 * <p>/*w  w w.  j av  a 2s .c  om*/
 * Obtains the list of locales to search through when performing a locale
 * search.

 * <pre>
 * localeLookupList(Locale("fr", "CA", "xxx"), Locale("en"))
 *   = [Locale("fr","CA","xxx"), Locale("fr","CA"), Locale("fr"), Locale("en"]
 * </pre>
 * 
 * <p>
 * The result list begins with the most specific locale, then the next more
 * general and so on, finishing with the default locale. The list will never
 * contain the same locale twice.
 * </p>
 * 
 * @param locale
 *            the locale to start from, null returns empty list
 * @param defaultLocale
 *            the default locale to use if no other is found
 * @return the unmodifiable list of Locale objects, 0 being locale, never
 *         null
