* @summary Enable resolveClass() to accommodate package renaming. |
|
29 |
* This fix enables one to implement a resolveClass method that maps a |
|
8559 | 30 |
* Serializable class within a serialization stream to the same class |
2 | 31 |
* in a different package within the JVM runtime. See run shell script |
32 |
