The issue was not reproducible and was showing up in particular machines (Where the machines are down now). So adding a screen capture to `BufferedImage` in case of failure so that it will help in analysis when the issue comes up in future.

GraphicsConfiguration gc = GraphicsEnvironment.
                         getLocalGraphicsEnvironment().getDefaultScreenDevice().getDefaultConfiguration();
                Rectangle gcBounds = gc.getBounds();

This way?
