I agree that this a nice feature, especially for headless tests as you also mentioned.
Really looking forward to this feature.

Betreff: Headless glass platform
Hi,
I created a branch in the jfx-sandbox repository for experimenting with a headless glass platform: https://github.com/openjdk/jfx-sandbox/tree/johanvos-headless
This addresses https://bugs.openjdk.org/browse/JDK-8324941 where I suggest a POC for a Headless platform.
There are a number of usecases for this, including:
1. applications that require JavaFX rendering without presenting this to a window (and instead send it to a printer for example)
1. applications that require JavaFX rendering without presenting this to a window (and instead send it to a printer for example)
2. running tests without requiring a window manager.
Regarding the second usecase, we already did some basic experiments using a modified version of TestFX where instead of the Monocle Headless subplatform, the POC Headless platform is used.
By using a first-class Headless glass platform instead of a Monocle subplatform, it should be easier to use by developers.
The monocle code contains very platform/os specific parts, which often don't make sense outside the target platform. This is very valuable, but it is also a very different usecase than a headless platform and it requires a much more complex build procedure.
I added an initial, limited HeadlessRobot to do some basic tests. That code is mainly taken from the existing Monocle implementation, but I want to be careful to avoid anything that is not applicable to the headless scenarios.
