I tested and can also confirm that the issue occurs without the latest patch, and is resolved now. Additionally I checked my own title bar test app.

When checking the controlsfx sampler app I do see CSS-related `ClassCastException`s in the "ComponentValidation" section, but they seem to be present with the current jfx master branch already.

The code changes look reasonable.
