A DESCRIPTION OF THE REQUEST : By retrieving a Charset object from FastCharsetProvider or AbstractCharsetProvider via charsetForName(String name), the canonical name of the charset is first lookuped from alias->canonical map, and 2ndly lookuped from canonical->charset map. JUSTIFICATION : Directly mapping from alias name to Charset instance by only 1 map would perform better. Additionally is would save some memory.
