How to override the back button on Android (NME recipe)

BackButtonExample.hx

import nme.display.Sprite;
import nme.Lib;


/**

class BackButtonExample extends Sprite {
	
	
	public function new () {
		
		super ();
		
		Lib.current.stage.addEventListener (KeyboardEvent.KEY_UP, stage_onKeyUp);
		
	}
	
	
	private function stage_onKeyUp (event:KeyboardEvent):Void {
		
		#if android
		
		if (event.keyCode == 27) {
			
			event.stopImmediatePropagation ();
			Lib.exit ();
			
		}
		
		#end
		
	}
	
	
}

Anyone know if this works in latest NME? Doesn't work for me.

Upgrade to openfl 1.0.4 works.
