The SWT.ON_TOP shell in the snippet below goes behind other windows when the application looses focus

import org.eclipse.swt.SWT;
import org.eclipse.swt.layout.*;
import org.eclipse.swt.widgets.*;


public class OnTopIssue {
public static void main(String[] args) {
	Display display = new Display();
	Shell shell = new Shell(display);
	shell.setText("main");
	shell.setLayout(new GridLayout(1, false));
	shell.setBounds(100, 100, 200, 200);

	Shell onTop = new Shell(display, SWT.SHELL_TRIM | SWT.ON_TOP);
	onTop.setText("ontop");
	onTop.setBounds(130, 130, 200, 200);
	Button button = new Button(onTop, SWT.PUSH);
	button.setText("Push");
	button.pack();
	onTop.open();

	Shell s = new Shell(onTop, SWT.DIALOG_TRIM | SWT.APPLICATION_MODAL); //works
//	Shell s = new Shell(onTop, SWT.DIALOG_TRIM); //works
//	Shell s = new Shell(SWT.DIALOG_TRIM); //fails on Windows, Cocoa, Carbon
	s.setBounds(150, 150, 200, 200);
	s.setText("dialog");
	Button button1 = new Button(s, SWT.PUSH);
	button1.setText("Push");
	button1.pack();
	s.open();

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