Hi,

Please review fix for JDK-8071929.
Bug :  https://bugs.openjdk.java.net/browse/JDK-8071929

patch : http://cr.openjdk.java.net/~rgoel/JDK-8071929/webrev.01/

Fix is to remove obsolete country code "AN" and provide support for 
retrieving of ISO3166-1 alpha-2, ISO3166-1 alpha-3, ISO3166-3 country codes.
