You're going about this slightly the wrong way. By the time your code is called you've missed the chance for these properties to have any effect.

You need to create an RmiRegistry and then create a JMXConnectorServer linked to the platform MBeanServer like this:

private void createJmxConnectorServer() throws IOException {
    LocateRegistry.createRegistry(1234);
    MBeanServer mbs = ManagementFactory.getPlatformMBeanServer();
    JMXServiceURL url = new JMXServiceURL("service:jmx:rmi://localhost/jndi/rmi://localhost:1234/jmxrmi");
    JMXConnectorServer svr = JMXConnectorServerFactory.newJMXConnectorServer(url, null, mbs);
    svr.start();
}
