When running this modified version of the JavaFX/Swing integration example from oracle.com on a Mac PowerBook w/retina display, major performance problems can be seen. The JavaFX scene takes 30 to 45 seconds to display when the "Open Dialog" button is pressed. There's no performance issue on my iMac, Windows 7 HP Desktop, or 17' PowerBook.
