Hi,
such problems arise every time JPA (or other persistence frameworks) 
entities are published (via REST in your case) without any 
transformation (the DTO pattern): I am afraid there is any cleaner 
solution than converting your Hibernate entities into something simpler.

BTW: which version are you using?
