We have samples showing how to build and run JavaFX applications using GraalVM. See our blog post [1] with samples [2].
Keep in mind that JavaFX has some characteristics that make it non-trivial to apply native-image out of the box (reflection/jni configuration, platform-specific static libraries, including resources and bundles...). This is why we created Gluon Substrate [3], which does most of this work: Developers use a maven plugin [4] (gradle will be ready soon too) and this is used in the samples [2]. If you use GraalVM native-image without all the parameters that Gluon Substrate adds, you will most likely create a "fallback-image" that still require a JVM and some other resources to be available at runtime, and this can give strange results. While I don't exclude JavaFX bugs will surface using this approach, I think it's more likely you're seeing issues due to this "mixed mode". - Johan [1] https://gluonhq.com/gluon-substrate-and-graalvm-native-image-with-javafx-support/ [2] https://github.com/gluonhq/client-samples [3] https://github.com/gluonhq/substrate [4] https://github.com/gluonhq/client-maven-plugin On Wed, Nov 20, 2019 at 10:22 PM Michael Paus <m...@jugs.org> wrote: > Hi, > > I would just like to know where JavaFX problems or bugs should be reported > which are strictly related to running on the just released GraalVM 19.3 > with > Java 11 support.
