Thank you for your time & efforts to research this problem. I landed up attaching an empty HashSet() to the roles as clientDcl.setRoles( new HashSet() ); That got rid of the exception. And, you are right about the fact that something (hibernate) was trying to get to the ClientDcl object and it's roles member variable way before even Castor got a chance at it!
