MergedBundle

public class MergedBundle extends ResourceBundle
Special resource bundle which delegates to two others. Ideally could just set the parent on the first, but this is protected, so it might not work. It's still unclear whether that approach would work in this subclass because it may break the localization fall through mechanism if used. Note: This code is copied from NbBundle in the openide sources with the following modifications: - reformatting - making variables final - renaming variables and some params - removing locale code - creating the merged set of keys using jdk classes and not nb utils
