Install java-openjfx

Install java-openjfx through your package manager. (or whatever means you used to install Java on your machine) Note that java-openjfx is compatible with OpenJDK8, not previous versions.

After installing java-openjfx, you may have to add it manually to your IDE SDK classpath. Eg in IntelliJ, you may have to go to Project Structure | SDKs | <select your SDK> | Classpath | + (the Classpath +, not the SDKs +) | and add /usr/lib/jvm/java-8-openjdk/jre/lib/ext/jfxrt.jar (which should be there now that java-openjfx has been installed) | OK
