Question

I’m trying to start a JMXConnectorServer for management and debug purposes. But I don’t want this service to prevent application from exiting normally when the last non-daemon thread is terminated.

In other words, I want the following program to terminate immediately:

public class Main {
    public static void main(final String[] args) throws IOException {
        MBeanServer mbs = ManagementFactory.getPlatformMBeanServer();
        JMXServiceURL jmxUrl = new JMXServiceURL("rmi", null, 0);
        JMXConnectorServer connectorServer =
            JMXConnectorServerFactory.newJMXConnectorServer(jmxUrl, null, mbs);
        connectorServer.start();
    }
}

String port = getProperty("com.sun.management.jmxremote.port");
if (port == null) {
    port = String.valueOf(getAvailablePort());
    System.setProperty("com.sun.management.jmxremote.port", port);
    System.setProperty("com.sun.management.jmxremote.ssl", "false");
    System.setProperty("com.sun.management.jmxremote.authenticate", "false");

    sun.management.Agent.startAgent();
}
log.info(InetAddress.getLocalHost().getCanonicalHostName() + ":" + port);
