1. Yep, I've verified whether my solution works for AWT and indeed it does: returning NO from canBecomeMain/KeyWindow does prevent OS from bringing window to the front. Wonder why it doesn't work for FX. The thing is, if we allow OS to bring blocked window to the front, even for a fraction of second required to restack window back, then user would see window jumping forth and back in z-order, and this is something we want to avoid.
2. I need to check on this. Thanks for pointing it out.

> 1. Even though you return NO from canBecomeMain/KeyWindow, the OS will still bring the window to front of the z-order when you click it. In FX we handle this by always returning YES from canBecome* methods, however, the windowDidBecomeKey: sends a special FOCUS_DISABLED event if the window is blocked. In that case the upper level code re-stacks windows so that the blocker window always appears on the top of the z-order. Have you verified if this works fine for AWT apps with your fix?

>> Please review a fix for 7124376: [macosx] Modal dialog lost focus. One can easily reproduce this bug by launching SwingSet2, choosing JOptionPane demo and then clicking "Show Message Dialog" button. Now, click on the "SwingSet2" window title bar and you'll see the window rapidly gaining and loosing focus.
