-/**
- * This is a convenient class for loading some of internal resources faster
- * if they are built with Resources.gmk defined in J2SE workspace. Also,
- * they have to be in class file format.
- *
- * "LOCALE_LIST" will be replaced at built time by a list of locales we
- * defined in Defs.gmk. We want to exclude these locales from search to
- * gain better performance. For example, since we know if the resource
- * is built with Resources.gmk, they are not going to provide basename_en.class
- * & basename_en_US.class resources, in that case, continuing searching them
- * is expensive. By excluding them from the candidate locale list, these
- * resources won't be searched.
- *
- * @since 1.6.
