Francisco Lozano commented on MHIBERNATE-109:
---------------------------------------------
If we use @CollectionOfElements instead of @ElementCollection, our
Map<String,Object> gets proper DDL generated.
If we use @ElementCollection, we get the error.
@ElementCollection private Map<String,String> data = new
HashMap<String,String>();
