Example 5 with NotificationListener

use of javax.management.NotificationListener in project jdk8u_jdk by JetBrains.

the class RMIExitTest method test.

private static void test() {
    try {
        JMXServiceURL u = new JMXServiceURL("rmi", null, 0);
        JMXConnectorServer server;
        JMXServiceURL addr;
        JMXConnector client;
        MBeanServerConnection mserver;
        final ObjectName delegateName = new ObjectName("JMImplementation:type=MBeanServerDelegate");
        final NotificationListener dummyListener = new NotificationListener() {

            public void handleNotification(Notification n, Object o) {
                // do nothing
                return;
            }
        };
        server = JMXConnectorServerFactory.newJMXConnectorServer(u, null, mbs);
        server.start();
        addr = server.getAddress();
        client = JMXConnectorFactory.newJMXConnector(addr, null);
        client.connect(null);
        mserver = client.getMBeanServerConnection();
        String s1 = "1";
