      Description

        After upgrading to the latest xcode(14.2)+macOS(12.6.1 or 13.0.1) I have found that some of the robot related tests start to fail.

        The root cause is here:
        https://github.com/openjdk/jdk/blob/master/src/java.desktop/macosx/native/libawt_lwawt/awt/CRobot.m#L352

        Note that we would like to get from native kCGBitmapByteOrder32Host and kCGImageAlphaPremultipliedFirst
            CGContextRef jPicContextRef = CGBitmapContextCreate(
                                                    jPixelData,
                                                    picWidth, picHeight,
                                                    8, picWidth * sizeof(jint),
                                                    picColorSpace,
                                                    kCGBitmapByteOrder32Host |
                                                    kCGImageAlphaPremultipliedFirst);

        But kCGBitmapByteOrder32Host might not be what we expected in the java.
        And looks like the kCGImageAlphaPremultipliedFirst is always wrong:
