I'm running Mac OS X Snow Leopard and wan't to access the Display from the activator in an OSGi bundle.

Below is the start method for my activator:

@Override public void start(BundleContext context) throws Exception { ExecutorService service = Executors.newSingleThreadExecutor(); service.execute(new Runnable() {

		@Override
		public void run() {
			Display display = Display.getDefault();
			Shell shell = new Shell(display);
			Text helloText = new Text(shell, SWT.CENTER);
			helloText.setText("Hello SWT!");
			helloText.pack();
			shell.pack();
			shell.open();
			while (!shell.isDisposed()) {
				if (!display.readAndDispatch())
					display.sleep();
			}
			display.dispose();
		}
	});
}

Calling this code in a Windows environment works fine, but deploying on Mac OS X I get the following output:

I've used the -XstartOnFirstThread VM argument without any luck. I'm on 64-bit Cocoa but I've also tried 32-bit Cocoa.

When trying on Carbon I get the following error:

Invalid memory access of location 00000020 eip=9012337c

When debugging into the Display class I can see that the Displays[] array only contains null references.
