<AWT Dev> [8] RFR for 8150258: [TEST] HiDPI: create a test for multiresolution menu items icons

[Alexander Stepanov]

Hello Sergey,

When running the following trivial test case (having Color set to 
"Generic RGB Profile")

import java.awt.*;

public class ColorTest extends Frame {

     private void UI() {
         setSize(100, 100);
         setBackground(Color.BLUE);
         setVisible(true);
     }

     public ColorTest() throws Exception {
         EventQueue.invokeAndWait(this::UI);
     }

     public static void main(String[] args) throws Exception {
         ColorTest test = new ColorTest();
         Thread.sleep(1000);

         Point pt = test.getLocationOnScreen();
         System.out.println("color = " +
             (new Robot()).getPixelColor(pt.x + 50, pt.y + 50));
         test.dispose();
     }
}

the expected output appears:

color = java.awt.Color[r=0,g=0,b=255]

At the same time the Color for the Icon is "[r=0,g=0,b=248]"

Could you please let me know if the test still fails for you when simply 
set "expected = C2X" on the ln 116 and comment out the 1st "@run"?

Not sure if it should be considered as a bug, or some additional 
settings are required, or the color check should be simply softened 
(some tolerance used).

Thanks,
Alexander
