Examples of my.code.a003.process.A05GetOwnPidUsingJvmstat

my.code.a003.process.apps.PrintOnRemoteRequest.MessagePrinterMBean
Print process ID. How can a Java program get it's own process ID? Way using {@link sun.jvmstat.monitor.MonitoredHost#activeVms()}
Limitation: This way fails when multiple class have the same class, when this application was launched several times.
Limitation: I am not sure how this will react when application is launched as executable JAR (java -jar foo.jar)

      // connect to child process via MBeans
      JMXServiceURL jmxURL = extractJmxServiceUrl(pid);
      JMXConnector connector = JMXConnectorFactory.connect(jmxURL);
      MBeanServerConnection mbsc = connector.getMBeanServerConnection();
      ObjectName mbeanName = new ObjectName("my.code.a003.process:type=PrintOnRemoteRequest.MessagePrinter");
      MessagePrinterMBean printerProxy = JMX.newMBeanProxy(mbsc, mbeanName,
        MessagePrinterMBean.class, true);


      // call method on child process via MBean
