0N/A * @summary If the type of a parameter or return value in an RMI call can be
0N/A * successfully downloaded by the receiving endpoint, then an array class with
0N/A * that type as its element type should likewise be able to be successfully
0N/A * downloaded. This should be true regardless of how many dimensions the
0N/A * array has.
