JDK-8169589 - [macosx] Activating a JDialog puts to back another dialog
Description
This regression test is to JDK-8169589 fix for a regression in CPU17_01. Apparently it does fix the issue on OS X (where reported) but doesn't on Windows. I have the test failing consistently on Windows 10.

RULE "java/awt/Dialog/DialogAboveFrame/DialogAboveFrameTest.java" Exception java.lang.RuntimeException: Test FAILED: Dialog is behind the frame
Comments
The problem reported under JDK-8169589 is OSX specific issue. It doesn't take place on Windows platform. There is a problem in the test. The test displays a frame and a dialog; then it checks the pixel's color to test whether the dialog is above the frame or not. It looks like drawing operation on Windows works a bit slowly than on OSX and the pixel doesn't have desired color when we examine it. Fix: The test should use Util.testPixelColor() from regtesthelpers package which is specially designed for asynchronous window manager.
