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