35 * @summary To test SystemFlavorMap method:
36 *          setNativesForFlavor(DataFlavor flav, String[] natives)
37 *          with valid natives and DataFlavors. This stress test will
38 *          define numerous mappings of valid String natives and
39 *          DataFlavors.  The mappings will be verified by examining
40 *          that all entries are present, and order is maintained.
