27 * @build install/SerialDriver.java test/SerialDriver.java extension/ExtendedObjectInputStream.java
28 * @summary Enable resolveClass() to accommodate package renaming.
29 * This fix enables one to implement a resolveClass method that maps a
30 * Serializable class within a serialization stream to the same class
31 * in a different package within the JVM runtime. See run shell script
32 * for instructions on how to run this test.
