Bounds obtained from the graphics device configuration created from a BufferedImage are no longer real.
Starting from Java 9, they always return (0, 0, Integer.MAX_VALUE, Integer.MAX_VALUE), which are very huge bounds!
Rectangle bounds = new BufferedImage(800, 600, BufferedImage.TYPE_3BYTE_BGR)
.createGraphics()
.getDeviceConfiguration()
.getBounds();
System.out.println(bounds);The test shows how Java 8 has the expected behaviour while Java 9 surprises us.

The JDK-issue JDK-8072682 and the associated commit show this is intentional. Yet we can seriously question the solution applied to the cache problem described in the bug report.
