        //   This test avoids returning empty arrays.

        //   but this should be indicated by an empty string for compatibility

        //   with JRE resource bundles.

        // - Finally, CLDR doesn't really have string arrays; each string is

        //   supposed to be inherited separately. Although value is the partially filled array,

        //   we will return it so that it can be reconstructed later in the method,

        //   ConvertLocaleData.convertBundles()
