Note: Remote connection tested using ssh to localhost or an actual remote machine.

Test w/ proper X11 authentication, i.e. DISPLAY and xauth:

> cd projects/JOGL/jogl-bugs/597-headless/
> echo $DISPLAY
localhost:10.0

> xclock
'works'

T1.1 OK> java plop 
jogamp.opengl.x11.glx.X11GLXDrawableFactory@f581593

T1.2 OK> java -Djava.awt.headless=true plop 
jogamp.opengl.x11.glx.X11GLXDrawableFactory@6f34a7d8

+++

Test _without_ proper X11 authentication, i.e. DISPLAY and xauth:

> xclock
No protocol specified
No protocol specified
Error: Can't open display: :0.0

T2.1 OK> java plop 
No protocol specified
No protocol specified
Exception in thread "main" java.lang.InternalError: Can't connect to X11 window server using ':0.0' as the value of the DISPLAY variable.
   (Stack trace from: 
        GLProfile.initProfilesForDefaultDevices(..) ->
        NativeWindowFactory.initSingleton(..) -> 
        JAWTUtil.<clinit>->
        sun.awt.X11.XToolkit.<clinit> ->         
        sun.awt.X11GraphicsEnvironment.initDisplay(Native Method)

T2.2 ERROR> java -Djava.awt.headless=true plop

SIGSEGV!!

-> confirmed.

Thx for reporting.
