Monocle uses the same Quantum toolkit that other JavaFX implementation use - not StubToolkit, which is only used in testing.

As I see it, there is a place for tests using StubToolkit, and a place for tests using a real Toolkit implementation. For example, QuantumToolkit has a very specific threading model, but this is not enforced by StubToolkit. StubToolkit is useful for isolated tests of the upper parts of the JavaFX stack. For a real application you need to test on a real Toolkit, and headless Monocle is one way to do that.

We have https://javafx-jira.kenai.com/browse/RT-35330 open on removing StubToolkit. I’m not convinced that is the right thing to do. https://javafx-jira.kenai.com/browse/RT-35396 would open up possibilities for a new class of automated test, without requiring us to rewrite existing tests that use StubToolkit.

Thanks,
Daniel
