 *          addUnencodedNativeForFlavor(DataFlavor flav, String nat)
 *          with valid natives and DataFlavors. This stress test will
 *          define numerous mappings of valid String natives and
 *          DataFlavors.  The mappings will be verified by examining
 *          that all entries are present.
