ProfilerAPI : Warning: invalid event handle in endComment

Question

hi
I try to use ProfilerAPI as described in the javadoc for the oracle.jdeveloper.profiler package (in JDeveloper 10.1.2.0.0).
I created a "Frame" using the wizard in the New Gallery and added a main method and the ProfilerAPI code like this:
package profilertest;
import javax.swing.JFrame;
import java.awt.Dimension;
import oracle.jdeveloper.profiler.ProfilerAPI;
public class ProfilerTestFrame extends JFrame
     private static final int PROFILER_TEST_EVENT_ID = 601;
     private static final boolean PROFILER_TEST_EVENT_ON =
          ProfilerAPI.isActive
          && ProfilerAPI.isEventActive(PROFILER_TEST_EVENT_ID);
     public ProfilerTestFrame()
          try
               jbInit();
          catch(Exception e)
               e.printStackTrace();
     private void jbInit() throws Exception
          if (PROFILER_TEST_EVENT_ON)
               ProfilerAPI.startEvent(PROFILER_TEST_EVENT_ID,
                    "Calling setBindingContext() on panels. (startEvent)");
          this.getContentPane().setLayout(null);
          this.setSize(new Dimension(400, 300));
          this.setTitle("Profiler Test");
          if (PROFILER_TEST_EVENT_ON)
               ProfilerAPI.endEvent(PROFILER_TEST_EVENT_ID,
                    "Calling setBindingContext() on panels. (startEvent)");
     public static void main(String[] args)
          JFrame vFrame = new ProfilerTestFrame();
          vFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
          vFrame.show();
}If I configure the Events Profiler in my Project Properties, I get to see the event in the Event Profiler window, but the "End" column keeps showing "Pending" for this event. In the log window I get "Warning: invalid event handle in endComment".
What am I doing wrong?
And by the way, are there "standard APIs" for this I can use, so I don't have to "couple" my code to this JDeveloper specific API.

Thanks Shay and 334369
My mistake, I must RTFM properly!
This looks more like it:
package profilertest;
import javax.swing.JFrame;
import java.awt.Dimension;
import oracle.jdeveloper.profiler.ProfilerAPI;
public class ProfilerTestFrame extends JFrame
     private static final int PROFILER_TEST_EVENT_ID = 601;
     private static final boolean PROFILER_TEST_EVENT_ON =
          ProfilerAPI.isActive
          && ProfilerAPI.isEventActive(PROFILER_TEST_EVENT_ID);
     public ProfilerTestFrame()
          try
               jbInit();
          catch(Exception e)
               e.printStackTrace();
     private void jbInit() throws Exception
          int vEventHandler = -1;
          if (PROFILER_TEST_EVENT_ON)
               vEventHandler = ProfilerAPI.startEvent(PROFILER_TEST_EVENT_ID,
                    "Calling setters on the frame. (startEvent)");
          this.getContentPane().setLayout(null);
          this.setSize(new Dimension(400, 300));
          this.setTitle("Profiler Test");
          if (PROFILER_TEST_EVENT_ON)
               ProfilerAPI.endEvent(vEventHandler,
                    "\nCalling setters on the frame. (endEvent)");
     public static void main(String[] args)
          JFrame vFrame = new ProfilerTestFrame();
          vFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
          vFrame.show();
}greetings
