ClassFormatError when running RMI between kaffe1.0.6 and jdk1.2.2

[Yun Zhang]

I have compiled a simple Java RMI program using Kaffe kjc and rmic. I
ran the server under Kaffe on node A and ran the client under Sun
jdk1.2.2 on node B. Both of machines are RedHat linux. The client side
generated the following error:
        Exception in thread "main" java.lang.ClassFormatError:

Does anyone has the similar experience or an explanation for this?  

Thank you for your help.
