Let me start by deeply thanking you for providing a better alternative for JemmyFX. I've been so reluctant to start writing tests because of the framework, but TestFX simply works as I expect.

That said, I'm already running into my first issue. I have a control that has CSS styleable properties called ListSpinner (available in JFXtras, similar to Swing's Spinner component). One of these properties is the "arrow direction", which allows positioning the arrow horizontally or vertically. In horizontal mode there is a right-arrow and left-arrow class assigned, in vertical mode an up-arrow and down-arrow. The tests I am writing is to assert each arrow has the correct behavior, right/up increments, left/down decrements. Default is the horizontal mode

First I try to set the arrow direction through CSS, like so:

spinner.setStyle("-fxx-arrow-direction: " + ListSpinnerCaspianSkin.ArrowDirection.VERTICAL);

That results in an exception:

java.lang.IllegalStateException: Not on FX application thread; currentThread = main

So I move it into a runAndWait method:

PlatformUtil.runAndWait( () -> {

spinner.setStyle("-fxx-arrow-direction: " + ListSpinnerCaspianSkin.ArrowDirection.VERTICAL);

});

That also results in an exception.
