btw, your stack trace says com.amazon.kindle.apps.util.resources.AreasResourc es, not UtilResources. Typo or intentional?
In any case, this method of "augmenting" resources via .properties files should work for either bundle. It's exactly the same method that is used for localization. So in this case, you're simply providing a more specific file (_en, or even _en_US) which will take priority over the base bundle. No need to tamper with class bytecode.
