I don't think it necessarily disables x-org dependencies. It turns off 
creation of windows and allows Java application to work without DISPLAY, 
but a lot of x-org graphic routines might still be used. 
"java.awt.headless" is used to do grapic in batch more. java.awt is 
still heavely used in this mode.
