 * @bug 4070080
 *
 * @build WriteAddedSuperClass ReadAddedSuperClass2
 * @run main ReadAddedSuperClass2
 * @summary  2nd part of test deserializes the serialization stream into an
 *           instance of the original class WHEN the AddedSuperClass exists
 *           locally.
 *
 * Description of failure:
 *
 * If you delete AddedSuperClass.class before running this test,
 * both JDK 1.1.x and 1.2 result in ClassNotFoundException for class
 * AddedSuperClass.  If the .class file is not deleted, 1.2 does not
 * fail. However, JDK 1.1.4 core dumps dereferencing a null class handle
 * in the native method for inputClassDescriptor.
