A DESCRIPTION OF THE PROBLEM :
When creating an image with a large dimension (width and/or height >= 32768), the image is no longer rendered in the JPanel on the window. This seems to affect at least java versions 8, 11, and 17. Also, overriding the paint method of the JPanel using drawImage produces the same result. It only renders with both dimensions < 32768. Exporting the BufferedImage to the filesystem produces expected results, so it seems the issue is at the rendering stage.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Create a JFrame with a JPanel contained by a JScrollpane.
2. Create a random image of either width or height >= 32768 pixels
3. Add this image to a JLabel and to the JPanel

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Fully rendered image on the window
ACTUAL -
Blank background of the window
