The fallback mechanism for ResourceBundle.getBundle appears to be broken. When I call getBundle on a locale for which the resource bundle does not exist, it falls back to the default locale's version of the bundle rather than the root locale's version. For example, say I have two resource bundles:

public class MyBundle extends ListResourceBundle {
    protected Object[][] getContents() {
        return new Object[][] { { "key", "root" } };
    }
}

public class MyBundle_en_US extends ListResourceBundle {
    protected Object[][] getContents() {
        return new Object[][] { { "key", "en_US" } };
    }
}

The following test program will access MyBundle_en_US rather than MyBundle:

public class BundleBug {
    static public void main(String[] args) {
        Locale.setDefault(Locale.US);
        ResourceBundle rb = ResourceBundle.getBundle("MyBundle",
                                              Locale.UK);
        String str = rb.getString("key");
        if (!str.equals("root")) {
            throw new RuntimeException("Expected 'root', got '"
                                       + str + "'");
        }
    }
}

When you run this, you get:
java.lang.RuntimeException: Expected 'root', got 'en_US'
        at BundleBug.main(BundleBug.java:15)
