I'm interested in headless testing, too. I tried to use StubToolkit for including TestFX tests in a headless build, but all I got was a CNFE. If anyone is interested to give me a hand on this, details can be found at

As Tom explained, Monocle would provide another way for headless testing. Does it replace StubToolkit?

What also is very interesting is headless testing. Let me see if I'm getting this. 
Normally Jenkins would start a VNC server (xvnc), which provides some kind of graphics API against which an UI program can paint. JavaFX is not picking that up however. 
But, as I read it, in this case JavaFX starts its own VNC server, so it takes of everything itself. All one would need to do is specify the 
     -Dglass.platform=Monocle -Dmonocle.platform=VNC -Dprism.order=sw 
And additionally a port to run the VNC server on (so multiple Jenkins jobs don't interfere). 
Am I correct? How can I test this (aka in which version is the VNC server available)?
