Why is JavaFX is not included in OpenJDK 8 on Ubuntu Wily (15.10)?

I've downloaded OpenJDK 8 today via `sudo apt-get install openjdk-8-jdk` and it seems like JavaFX is not included in it. > java -version openjdk version "1.8.0_66-internal" OpenJDK Runtime Environment (build 1.8.0_66-internal-b17) OpenJDK Server VM (build 25.66-b17, mixed mode) I've installed E(fx)clipse in latest Eclipse (Eclipse Mars) too, but I'm still getting message *javafx couldn't be resolved*.
