Retina/high-DPI custom cursor in Java?

Question

Is there any way to support high-resolution displays for Java custom cursors? The usual method seems to be using Toolkit:

Toolkit.getDefaultToolkit().createCustomCursor(cursorImage, new Point(), "customCursor");

However, there is very little control over the cursor itself. Is there some method to do this which supports high-DPI displays, or will I need to hide the cursor and paint it manually?
