Specifying the error:
Caused by: java.lang.IllegalArgumentException: Can not set 
sessions.RFBServiceSession field 
GeneratedRuleSet_RFBServiceSession.startingPoint to 
GeneratedRuleSet_RFBServiceSession

public class GeneratedRuleSet_RFBServiceSession implements 
runtime.CompiledRuleSet {
    private static final long serialVersionUID = 1L;
    private volatile sessions.RFBServiceSession startingPoint;
    private static volatile Object undefined = null;
    private volatile java.lang.StringBuilder debugSB;   

    public GeneratedRuleSet_RFBServiceSession() {
        super(); 
    }

    @Override
    public runtime.CompiledRuleSet clone() {
        return new GeneratedRuleSet_RFBServiceSession();
    }
}

Thanks fo the help!

With Java DeepCloner it works without any error.

hard to tell what might be causing this. Any chance you provide a test that 
fails with a similar error?

It's not that simple because it's a integration test that uses more than one 
system.
Any ideas who the problem can be?

Sorry, can't tell. So sessions.RFBServiceSession is RFBServiceSession in 
package sessions right? And GeneratedRuleSet_RFBServiceSession seems to be an 
other class.

RFBServiceSession is a class in package named "sessions".
GeneratedRuleSet_RFBServiceSession is other class in other package 
(utils.GeneratedRuleSet_RFBServiceSession).

We made more tests and the behaviour is strange. The test always pass with 
success once. If we execute again fails!

The class GeneratedRuleSet_RFBServiceSession is generated and instanciated in 
runtime, by a rule compiler system.

We keep data in a in-memory data grid (Oracle Coherence).

can you please (if possible) create a simple test case and reopen this? I can't 
figure out what might be wrong
