Title:
  Robot.createScreenCapture() does not work with unity-2d

Status in OpenJDK:
  New
Status in “openjdk-6” package in Ubuntu:
  Confirmed
Status in “openjdk-7” package in Ubuntu:
  Confirmed

Bug description:
  The built in Java screen grabber
  (java.awt.Robot.createScreenCapture(...)) does not work correctly with
  unity-2d. When attempting to create a screen capture for the whole
  screen only the dash and menu bars are captured - everything else is
  black. This only affects unity-2d not unity or KDE.

  Simple test case:

  import java.awt.*;
  import java.awt.image.BufferedImage;
  import java.io.File;
  import javax.imageio.ImageIO;

  public class ScreenGrab {
    public static void main(String[] args) {
      try {
        Rectangle grabRect = new Rectangle(Toolkit.getDefaultToolkit().getScreenSize());
        Robot robot = new Robot();
        BufferedImage capture = robot.createScreenCapture(grabRect);
        ImageIO.write(capture, "PNG", new File("java-screen-shot.png"));
      } catch (Exception e) {
        e.printStackTrace();
      }
    }
  }
