---------- BEGIN SOURCE ----------
public void captureScreen() throws AWTException {
    Robot robot = new Robot(GraphicsEnvironment.getLocalGraphicsEnvironment().getDefaultScreenDevice());
    BufferedImage screen = robot.createScreenCapture(new Rectangle(getDefaultToolkit().getScreenSize()));
    try {
        ImageIO.write(screen, "jpg", new File("/tmp/screenshot.jpg"));
    } catch (IOException e) {
        e.printStackTrace();
    }
}

CUSTOMER SUBMITTED WORKAROUND :
None. A Wayland developer commented the following:
This is not a Wayland bug, this is a problem with java.awt.Robot. Report it to the proper place. Let them know that they can take screenshots with dbus or with wlr-screencopy, depending on the wayland compositor in question.

FREQUENCY : always
