Hi,

I tried using swt from eclipse.My xulrunner version is 1.8.1.2.but the
below code crashes after loaduri , progress listerner says it is
loading and after sometime it crashes.This is on linux.Do you see any
issues in my usage.

public TestGTK(Composite parent, int style)
	{
		super(parent,style);
	}

	public static void main(String[] args)
	{
		System.out.println("user.dir "+System.getProperty("user.dir"));
		//Browser brow =  new Browser();
		Display display = new Display();
		Shell shell = new Shell(display);
		shell.setBounds(300, 300, 300, 300);
		shell.setText("Main Window");
		TestGTK gtk =  new TestGTK(shell,SWT.EMBEDDED);
		gtk.initDisplay(shell);

		shell.open();
		gtk.test();
		while (!shell.isDisposed())
		{
			 if (!display.readAndDispatch())
			 		display.sleep();
		}

		display.dispose();
