+ * @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.
