It's a different definition of "headless". The JDK can have headful
capabilities but operate in headless-mode - all the libs are still
present. The SE-Embedded headless JRE has had all the headful libs
stripped out. We use the absence of the libs to recognize that this is
a headless-JRE and use that to set the java.awt.headless property so
that the Java libs act in headless-mode. So the VM drives this.
I guess I'm wondering if the absence check could be done in the AWT code
rather than in the VM.
The only glitch I see with that is that the
GraphicsEnvironment.getHeadlessProperty code is Java code while to check
for the native lib we'd need native code.
It's doable I guess, but is it worthwhile? What problem are we trying to
solve?
