@prrace the related API already throw SecurityException if capture permission is not granted. moreover the API has been changed already in the pastr to accommodate that eg see

 https://docs.oracle.com/javase/8/docs/api/java/awt/Robot.html#getPixelColor-int-int-

VS

https://docs.oracle.com/en/java/javase/21/docs/api/java.desktop/java/awt/Robot.html#getPixelColor(int,int)

and so it stands to reason that a similar solution can be found for this problem as well if there is a will to do so.

An exception seem to be the most logical solution here to me however it could be something different, like the approach you describe in JDK-8321475 (i cant comment there so commenting here instead). Either way, like i said, i firmly believe that the current API behavior is just plain wrong and potentially harmful.
