On bundle compiling with code

    package ihtika2.mainform;

import com.google.code.ihtika.Vars.Ini;
import ihtika2.mainform.service.MainFormInterface;
import java.util.HashSet;
import java.util.Hashtable;
import org.osgi.framework.Bundle;
import org.osgi.framework.BundleActivator;
import org.osgi.framework.BundleContext;
import org.osgi.framework.InvalidSyntaxException;
import org.osgi.framework.ServiceReference;
import org.osgi.framework.wiring.FrameworkWiring;

public class Activator implements BundleActivator {

    @Override
    public void start(BundleContext context) throws Exception {
        Hashtable<String, String> props = new Hashtable<String, String>();
        props.put("Funct", "MainForm");
        context.registerService(MainFormInterface.class.getName(), new MainForm(), props);

        ServiceReference[] refs = context.getServiceReferences(
                MainFormInterface.class.getName(), "(Funct=MainForm)");
        if (refs == null) {
            System.out.println("Not Found MainForm on start");
        } else {
            MainFormInterface MainForm = (MainFormInterface) context.getService(refs[0]);
            MainForm.sendContext(context);
            MainForm.showWindow();
        }

        int x = 0;
        for (Bundle qqq : context.getBundles()) {
            if (x < 1) {
                HashSet<Bundle> bundles;
                bundles = new HashSet<Bundle>();
                bundles.add(qqq);
                HashSet<Bundle> depends = (HashSet<Bundle>) context.getBundle(0).adapt(FrameworkWiring.class).getDependencyClosure(bundles);
                System.out.println("---");
                System.out.println(qqq.getSymbolicName());
                System.out.println("+++");
                for (Bundle depends1 : depends) {
                    System.out.println(depends1.getSymbolicName());
                }
            }
                x++;
        }

I get error

To see the full stack trace of the errors, re-run Maven with the -e switch.
Re-run Maven using the -X switch to enable full debug logging.

Please advice me, how to compile this code?
I use apache-maven-2.2.1, jdk1.7.0_06, compiling for the 1.6 code (setting in NetBeans project ).
What interesting – NetBeans doesn’t show error on this string (Activator.java:[38,109]) and consider this code correct.

    Problem is in the Felix 4.0.3 and org.osgi.core (4.3.0) jars bundles from Central Maven repo.

    I guess they are outdated.

    As far as I understand it, except Osgi version (4.3) has also revision.

    Probably the library at the central Maven repository outdated.

    The solution – download and compile the source from

    https://svn.apache.org/repos/asf/felix/trunk/ framework.

    Ie – after source download, in the folder with sources:

    cd framework

    mvn install

    It’s command will compile and install Felix to your local Maven repo. After this you can use new Felix’s bundle (SNAPSHOT) instead the bundles from the Central Maven repo.

    Sorry my bad English.
