Import vs full package name

Question

So, I decided to fumble a bit with JavaFX. After having gotten myself a sh*tload of stress doing stuff in Flash and Actionscript, I'm ready for something that is intended as "code" from the ground up. One thing I ran into is this: AFAIK I have two identical custom nodes, the only difference is that one uses full package names and the other uses imports. The components just show an image.
Full package version:
public class SfeerNode extends javafx.scene.CustomNode
    public var sfeerimage : javafx.scene.image.Image;
    override function create() : javafx.scene.Node
        return javafx.scene.Group
            content:
            [     javafx.scene.image.ImageView
                      image: sfeerimage
}And the import version:
import javafx.scene.*;
import javafx.scene.image.*;
import javafx.scene.paint.*;
import javafx.scene.shape.*;
public class SfeerNode2 extends CustomNode
    public var sfeerimage : Image;
    override function create() : Node
        return Group
            content:
            [     ImageView
                      image: sfeerimage
}Usage is very straight forward, just like ImageView, and I can toggle between the two by simply adding or removing "2" after "SfeerNode" in the main code.
The problem: the full package version does NOT show the image, the import version does.
Why?

It is definitely a bug.
It is possible to extend only CustomNode class to make the first sample work .
import javafx.scene.CustomNode;
public class A extends CustomNode {
    public var sfeerimage : javafx.scene.image.Image;
    override function create(): javafx.scene.Node{
        return javafx.scene.Group {
            content:[ javafx.scene.image.ImageView {
                      image: sfeerimage
}
