<AWT Dev> [9] Review request for 8065739 [macosx] Frame warps to lower left of screen when displayed

[Alexander Scherbatiy]

Hello,

Could you review the fix:
   bug: https://bugs.openjdk.java.net/browse/JDK-8065739
   webrev: http://cr.openjdk.java.net/~alexsch/8065739/webrev.00

   Use case:
   ------------
   Frame frame = new Frame();
   frame.pack();
   frame.setBounds(screenBounds);
   frame.setVisible(true);
   ------------

   The frame is in the normal state but Mac OS X treats a frame with 
screen bounds as zoomed.
   The setVisible() method calls unmaximize() method to return the 
zoomed window to the normal state.
   The native zoom() method sets the initial sizes for the window which 
are zero because of the pack() call.


   There is already checkZoom() method which synchronizes native window 
zoom state and and the frame extended state when a frame is resized by 
mouse.
   However it can't be always used for the synchronization between 
native window zoom state and setBounds() call because of the following case:

   -----------------
   Frame frame = new Frame();
   frame.setBounds(smallBounds);
   frame.setExtendedState(Frame.MAXIMIZED_BOTH);
   frame.setVisible(true);
   -----------------

   This is the valid scenario where the frame should be maximized.

   The solution synchronizes the zoom and the frame state only when the 
native window is zoomed.
   In opposite case we need to return from the zoomed sizes to previous 
sizes which are the same as for the zoomed window.

Thanks,
Alexandr.
