> OnDelete=OnDeleteAction.CASCADE on unidirectional OneToMany results in :
> "only inverse one-to-many associations may use on-delete="cascade"
> But in JPA we do not have bidirectional mapping. 
> My code is generated with hyperjaxB, so I have no possibility to make the relation bidirectional.
> I think OnDelete=OnDeleteAction.CASCADE must be possible together with orphanRemoval=true.
> (orphanRemoval=true for updates, and OnDelete=OnDeleteAction.CASCADE for deletes)
