Setup
-----------------
* WindowsXP
* Sun1.4.2_05
* JBoss3.2.3
* Janeva invoking JBoss via IIOP

I am getting a marshal exception when I call a session bean over iiop from my Janeva client. The object that I am passing in was previously unmarshalled on a previous successful call.

Example:
-----------
MyObject obj = svc.getMyObject();
obj.setName("foo");
svc.updateMyObject(obj);

The last call fails w/ the following exception:
