| 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 | * Serialiazable 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. |
