Problems importing/accessing javafx.* packages in JS FXML script

Question

I cannot figure out how to import access javafx.* packages in FXML JS-scripts. Currently trying the following, example code provided below:
FXML
<fx:script source="myscript.js"/>
<HBox fx:id="myBox" onDragDetected="featureDragDetected(event)" />
JS-script (myscript.js)
function featureDragDetected(event) {
  event.getSource().startDragAndDrop(javafx.scene.input.TransferMode.ANY);
I get the following error message:
javax.script.ScriptException: sun.org.mozilla.javascript.internal.EcmaError: ReferenceError: "javafx" is not defined. (<Unknown source>#6) in <Unknown source> at line number 6
  at com.sun.script.javascript.RhinoScriptEngine.eval(Unknown Source)
  at javax.script.AbstractScriptEngine.eval(Unknown Source)
  at javafx.fxml.FXMLLoader$ScriptElement.processStartElement(FXMLLoader.java:1323)
What am I doing wrong?

It works on my system.
MyClass.java
package com.foo.java;
public class MyClass {
    @Override
    public String toString() {
        return "My Class";
MyFXScript.fx
package com.foo.javafx;
import com.foo.java.*;
var myClass = new MyClass();
println(myClass);standard-run:
My Class
