Using mappedName on an @EJB in a JSF managed bean doesn't work.
DefaultAnnotationProcessor ignores mappedName and will then perform a standard field lookup <bean>/<field>, resulting in a NameNotFoundException.

16:12:46,859 ERROR [JBossInjectionProvider] Injection failed on managed bean.
javax.naming.NameNotFoundException: com.genloop.web.Projektabrechnung.Projektabrechnung_v13.beans.screen.Partner_Einzelperson_Screen not bound
