When testing IIOP in JBoss EAP 5.0.1 CR1, the warnings below are logged when a client first calls an EJB via IIOP. These are all methods that do not really exist on the bean, so they don't have any AOP interceptors governing their calls. In essence it's a fault of the container request such interceptors.
