Class cast exception points to a failure in TM4J, I guess. %)

You're doing something like the following?

   Topic t = tm.createTopic();
   Topic scopingTopic = tm.createTopic();
   TopicName tn = t.createTopicName("Hello", null);
   Variant var = tn.createVariant("World", null);
   var.addScopingTopic(scopingTopic);

   serialize(tm); // BOOOOM!

Best regards,
Lars
