51        //   This test avoids returning empty arrays.

53        //   but this should be indicated by an empty string for compatibility
54        //   with JRE resource bundles.
55        // - Finally, CLDR doesn't really have string arrays; each string is
56        //   supposed to be inherited separately. Although value is the partially filled array,
57        //   we will return it so that it can be reconstructed later in the method,
58        //   ConvertLocaleData.convertBundles()
