indeed Java 9 removed some packages from *core* java and were moved to
additional modules to add at compilation/runtime.
Problem is this is not transparent/compatible with java <= 8.
So, to support java 9 AND below, you need specific scripts that detect
java version and act accordingly. This is not really cool to do and
maintain.....

As proposed, either javafx can be removed from code, either we shoud
stick to Java 9 and superior and add the javafx module.
there is an example in biojava4 for a build.xml:


       <junit haltonfailure="yes" printsummary="yes" fork="true">
          <jvmarg line="--add-modules java.se.ee"/>
          <classpath refid="test.classpath"/>
          .....

this example used java.se.ee module.

For javafx, there are several modules [0]:

* Base APIs for JavaFX UI Toolkit — javafx.base
* JavaFX APIs for UI Controls — javafx.controls
* JavaFX APIs for FXML — javafx.fxml
* JavaFX APIs for various Graphics Tools— javafx.graphics
* JavaFX APIs for Multimedia — javafx.media
* JavaFX APIs for Swing-JavaFX Interoperability — javafx.swing
* JavaFX APIs for WebView Functionality — javafx.web


To add multiple modules, one need to separate them with comma.
