Can a StaleStateObjectException ever be thrown from a single thread?

We are using Grails and Hibernate. We are getting an org.hibernate.StaleObjectStateException in our logs. I see this can happen because of optimistic lock failure. Fine. However, I want to ensure this can never happen from multiple updates from the same thread. I mean never ever. Is there any corner case where there is multiple updates to the same hibernate entity but all from the same thread that can cause this exception?

Thanks,

I didn't try but I would expect this error from this code:

 Foo foo1 = session.get(Foo.class, 1);
 Foo foo2 = session.get(Foo.class, 1); // same ID

 foo1.setBar(1);
 foo2.setBar(2);

 session.saveOrUpdate(foo1);
 session.saveOrUpdate(foo2); // Should throw an error

This can happen, for example, when you have complex helper objects that work on the same entities.
