 * @summary Enable resolveClass() to accommodate package renaming.
 *          This fix enables one to implement a resolveClass method that maps a
 *          Serialiazable class within a serialization stream to the same class
 *          in a different package within the JVM runtime. See run shell script
 *          for instructions on how to run this test.
