Specification of Taskbar::getIconImage doesn't mention that the returned image might not be equal to the Taskbar::setIconImage one. (eg on Mac OS)

Specification of Taskbar::getIconImage doesn't mention that the returned image might not be equal to the one passed to Taskbar::setIconImage method (eg on Mac OS)

Code Snap:
public void testSetGetIconImage() {
        Image originalImage = new BufferedImage(100, 100, TYPE_INT_RGB);
        Taskbar taskbar = Taskbar.getTaskbar();
        taskbar.setIconImage(originalImage);
        Image newImage = taskbar.getIconImage();
        if (originalImage.equals(newImage)) {
            System.out.println("OK. GetIconImage returned image equal to set one");
        } else {
            System.out.println("FAILED: Expected equal to : "+ originalImage + ", was given:"+ newImage);
        }
}

Output:
Expected equal to : "BufferedImage@424c0bc4: type = 1 DirectColorModel: rmask=ff0000 gmask=ff00 bmask=ff amask=0 IntegerInterleavedRaster: width = 100 height = 100 #Bands = 3 xOff = 0 yOff = 0 dataOffset[0] 0", was given: "sun.awt.image.MultiResolutionCachedImage@66133adc"

If the following specs in fact don't assume that set/get methods must work in sync (getter is not required to return image that is equal to the one given to setter) - this needs to be mentioned explicitly.

public void setIconImage​(Image image)
"Changes this application's icon to the provided image."
public Image getIconImage()
"Obtains an image of this application's icon.
