/* Difference with EclipseLink
   This does not work for Hibernate as it manages override of annotations in JPA entities different than Eclipselink.
   Overriding this field and adding @Version for optimistic locking would not work (it does with EclipseLink).
   For optimistic locking with Hibernate this has to be added directly in the project classes.
