Monocle gone?

Indeed. I was waiting for Monocle to become part of the standard distribution, 8u20 was said a while back, so TestFX would be adapted and headless testing on Jenkins would be enabled. It would be very good that using Monocle would not require building JavaFX yourself, that makes the threshold unnecessarily high. It should IMHO at least be available as an easy download for inclusion via libs.
