Perhaps Anthony might be able to answer your question: he has tinkered a lot
with headless related stuff.
David, are you implying that in the current form my fix is no-go?
Not my place to do that. I'm just wondering how the HToolkit got
involved with OSX, and why OSX headless is handled differently to
Solaris/linux (which don't use HToolkit).

Hi,
Please review a fix for 7181027: [macosx] Unable to use headless mode. The problem here
is that for headless mode "java.awt.graphicsenv" system property should be
CGraphicsEnvironment because the way GraphicsEnvironment.createGE() method works: it
first instantiates GraphicsEnvironment instance and then wraps it with
HeadlessGraphicsEnvironment if in headless mode. This means twe can't use
java.awt.graphicsenv property to determine whether we are in headless mode or not. So,
I've replaced it with a toolkit check: if it's HToolkit, then we are in headless.
sun.awt.HToolkit was introduced for use by SE-Embedded's reduced headless JRE.
How did the OSX port end up using it ???
Headless handling on OSX should be like regular headless on Linux, Solaris.
