rmi problems with latest visad.jar

Hi,
When I switched to the latest visad.jar file I started getting exceptions like below. It works fine with an older version of visad.jar. I have been careful to make sure the rmiregistry, server, and client are all running with the same classpath. I have a RemoteServerImpl (with RemoteDataReferenceImpls) bound to my server but when I try to access the data from my client:
java.rmi.UnmarshalException: error unmarshalling return; nested exception is: java.io.WriteAbortedException: writing aborted; java.io.NotSerializableException: java.lang.Object

Any ideas?
