[9] Review request for 8151170: WINDOW_MODAL dialog does not popup when restoring iconified owner window, which causes application freeze

[Semyon Sadetsky]

Hello Kevin & David,

Please review the fix for jfx9:

bug: https://bugs.openjdk.java.net/browse/JDK-8151170

webrev: http://cr.openjdk.java.net/~ssadetsky/8151170/webrev.00/

Win32 API ::GetWindowRect() call returns fake -32000,-32000 location for 
iconified window. Solution: skip WM_MOVE if window iconified.
