RCP on OSX - Carbon, Cocoa, and SWT_AWT troubles... [message #488936]

I have been trying to get an RCP app that uses some Swing elements to work on the Mac platform. I personally don't care if I am using Carbon or Cocoa. I had heard from IRC and other posts that the SWT_AWT bridge isn't fully implemented for Cocoa on OSX, so I am trying to use Carbon instead. I downloaded the Carbon eclipse sdk and I am using the Carbon RCP SDK for my target. However, when I launch this toy test project, I still get errors about Cocoa. What is going on? I just want my RCP (with Swing) app to work in some way on OSX.

Here are the errors:

Closing down...

Here is the code for the toy application:

package headlesstest;

import javax.swing.JFrame;
import javax.swing.JLabel;

import org.eclipse.equinox.app.IApplication;
import org.eclipse.equinox.app.IApplicationContext;

/**
 * This class controls all aspects of the application's execution
 */
public class Application implements IApplication {

	/*
	 * (non-Javadoc)
	 * 
	 * @seeorg.eclipse.equinox.app.IApplicationstart(org.eclipse.equinox.app.
	 * IApplicationContext)
	 */

	public Object start(IApplicationContext context) throws Exception {
		System.out.println("Hello RCP World!");
		javax.swing.SwingUtilities.invokeLater(new Runnable() {
			public void run() {
				createAndShowGUI();
			}
		});
		Thread.sleep(10000);
		System.out.println("Closing down...");
		return IApplication.EXIT_OK;
	}

	private static void createAndShowGUI() {
		// Create and set up the window.
		JFrame frame = new JFrame("HelloWorldSwing");
		frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		// Add the ubiquitous "Hello World" label.
		JLabel label = new JLabel("Hello World");
		frame.getContentPane().add(label);
		// Display the window.
		frame.setSize(400, 400);
		frame.pack();
		frame.setVisible(true);
	}

	/*
	 * (non-Javadoc)
	 * 
	 * @see org.eclipse.equinox.app.IApplicationstop()
	 */
	public void stop() {
		// nothing to do
	}
}

This exact same code works just fine on a Linux machine. Please help!

I have the same problem with my RCP application and get the same error message with Carbon and Cocoa (32,64 bit).
Furthermore the error message occurs if i resize views which
embedd swing panels with the swt_awt bridge.
Any information about this error (and workaround)
is appreciated!
