I'm only going to generate the bean once during the life of the app (it's @ApplicationScoped). IIUC, thereafter the CreationalContext should be ignored.

Now, is the CreationalContext then stored with the bean instance and used for destruction automatically (seems that way in AbstractMapContext.destroy(Contexual) )?
