node won't shutdown

edit

Hello!

I'm using the rosjava_core revision 1084ec6c569c (from 24th of February) - the newest version is not an option for me, since I need actionlib.

I have a simple test program which works. When I run it, it will print "my work is done here" and "shutting down" in this order. But in eclipse IDE, the program keeps running! And when I run "rosnode list" on the bash, it will also tell me, that the node still exists.

When I press the red stop button in eclipse, eclipse tells me, the program is terminated, but I will still find the node with "rosnode list" on the bash.

How can I properly stop the program and kill the node? "rosnode kill /myNodeName2" does not kill the node neither, but I want to do it in java code, anyway, so this would not be an option.

Any help appreciated! Here's the code:

package my.package.tests_new_rosjava;

import java.net.URI;

import org.ros.address.InetAddressFactory;
import org.ros.namespace.GraphName;
import org.ros.node.DefaultNodeMainExecutor;
import org.ros.node.Node;
import org.ros.node.NodeConfiguration;
import org.ros.node.NodeMain;
import org.ros.node.NodeMainExecutor;

public class simpleTest {

    public static void main(String[] args) {

        String host = InetAddressFactory.newNonLoopback().getHostAddress()
                .toString();

        NodeConfiguration configuration = NodeConfiguration.newPublic(host,
                URI.create("http://localhost:11311"));
        configuration.setNodeName("myNodeName2");

        RosTasks objectsClient = new RosTasks();

        NodeMainExecutor runner = DefaultNodeMainExecutor.newDefault();
        runner.execute(objectsClient, configuration);

        while (!RosTasks.finished) {
            try {
                Thread.sleep(100);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
        }

        objectsClient = null;

        System.out.println("shutting down");
    }
}

class RosTasks implements NodeMain {

    public static boolean finished;

    @Override
    public void onShutdown(Node arg0) {

    }

    @Override
    public void onShutdownComplete(Node arg0) {

    }

    @Override
    public void onStart(Node node) {
        finished = false;

        System.out.println("my work is done here");

        finished = true;
    }

    @Override
    public GraphName getDefaultNodeName() {
        return null;
    }
}
