Hi David, hi Francis,
I checked in the attached patch to HeadlessGraphicsEnvironment. It now
tries to get hold of a CairoGraphics2D if available. It falls back to
the (Java-only) RasterGraphics only when nothing else works. David, can
you please test if this works?

Should you be using the Constructor 'bigC' here to create the 'g2d'
(passing the BufferedImage as an argument), and not the Class 'bigCl'?
