* @summary Enable resolveClass() to accommodate package renaming.
|
|
* This fix enables one to implement a resolveClass method that maps a
|
|
* Serializable 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.
