Hi David,
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?
Unfortunately your patch didn't change the outcome...
Strange. I suppose something goes wrong in the magic reflection code
that I added. Could you please add ex.printStackTrace() in the catch
block in HeadlessGraphicsEnvironment.createGraphics() to see what
exactly goes wrong and post this trace?

Hi Roman,
The mailing list seems slow, so hopefully this gets through...
I did that, then fixed the reflection code as attached. That results in
a NullPointerException fetching the name for a font (see below), I think
because the HeadlessToolkit is mostly stubs:
