If one tries to register/create the following MBeans in the MBenServer and then invoke mbs.getMBeanInfo(name).getNotifications() - an empty array will be returned.

1. A management interface is annotated with @NotificationInfo:
--------------------------------------------------------------
    @NotificationInfo(types={"com.example.notifs.create",
                             "com.example.notifs.destroy"})
    public interface CacheMBean {
         int getCachedNum();
    }

    public class Cache implements CacheMBean {

        public int getCachedNum() {
            return 0;
        }
    }
--------------------------------------------------------------

2. An MBean implementation class is annotated with @NotificationInfo:
--------------------------------------------------------------
    @MBean
    @NotificationInfo(types={"com.example.notifs.create",
                             "com.example.notifs.destroy"})
    public class Cache {
        @Resource
        SendNotification sn;
    
        @ManagedOperation
        public int getCachedNum() {
            return 0;
        }
    }
