This simple select in a transaction causes a @PreUpdate event to be triggered for every single selected entity:

em.getTransaction().begin();  
List result = em  
.createNamedQuery(“Stores.getAll”, Store.class)  
.getResultList();  
em.getTransaction().commit();

EclipseLink does not produce this bug.

Optimistic locking with @Version is used, no other specialities that I can think of.
