DESCRIPTION:

PROBLEM DESCRIPTION
Problem:
For testing interoperibility between SDK 5.0 & SDK 6.0 javax.swing.TransferHandler(null) is sent from a client to the server using RMI-IIOP.This is resulting in MarshalException.

The serialVersionUID of javax.swing.TranserHandler is different for Java5 and Java6.

Using Java5 and running the command
serialver javax.swing.TransferHandler
gives the result:
-3647487763055806389L;

Using Java6 and running the command
serialver javax.swing.TransferHandler
gives a different result:
7915941022583212167L;

STEPS TO REPRODUCE
------------------
Install latest SDK 6.0 on Windows IA32

Set PATH variable to point to bin and jre\bin folders

1. Compile all the testcases below - javac *.java

2. rmic -iiop HelloImpl

3. Issue these commands

start- \jdk5\sdk\jre\bin\tnameserv -ORBInitialPort 9009
Wait for the tnameserv to start
start- \jdk5\sdk\jre\bin\java
-Djava.naming.factory.initial=com.sun.jndi.cosnaming.CNCtxFactory -Djava.naming.provider.url=iiop://127.0.0.1:9009 Server
Wait for the server to start
start- \jdk6\sdk\jre\bin\java
-Djava.naming.factory.initial=com.sun.jndi.cosnaming.CNCtxFactory -Djava.naming.provider.url=iiop://127.0.0.1:9009 Client

You can see the following Exception:
