Currently the JavaFX value extractors are automatically registered if JavaFX is detected on the classpath.

This is problematic when classes from JavaFX are indeed available, yet not fully functional such as on the GraalVM (which is unreleases so I guess this is work in progress).

To be able to test other aspects it would be great to have the option to just disable this integration explicitly;
I'm going to contribute a patch proposel yet intentionally not listing it in documentation as I hope this to be a termporary workaround for the Graal team to fix soon.
