please see the attached test case.

With singleTable inheritance lazyLoad is triggered, without the discriminator value in the SQL Statement. In consequence there are wrong mapped objects in the collection. In the later, if the entityManager knows the wrong mapped object and the secound second collection triggerLazy load, there is a org.hibernate.WrongClassException thrown.
