[CSS] CHART_COLOR_XX not found

The base chart colors (aka: CHART_COLOR_1 etc) are not accessible.

To reproduce, run the example below and click "style"
expected: color of rectangle changes to first of the base chart colors
actual: color remains black, with following warning at the console:

Jan 27, 2015 2:55:27 PM javafx.scene.CssStyleHelper calculateValue
WARNING: Could not resolve 'CHART_COLOR_1' while resolving lookups for '-fx-fill' from inline style on Rectangle[x=0.0, y=0.0, width=300.0, height=400.0, fill=0x000000ff]

Behaviour in 8u20 was as expected, so it looks like a regression to me.

package de.swingempire.fx.scene.control.cell;

public class ChartColorCSS extends Application {

    public static void main(String[] args) {
        launch(args);
    }

    @Override
    public void start(Stage primaryStage) throws Exception {
        Rectangle r = new Rectangle(300, 400);
        Button button = new Button("style");
        button.setOnAction(e ->
            r.setStyle("-fx-fill:CHART_COLOR_1;"));
        HBox root = new HBox(r, button);
        Scene scene = new Scene(root);
        primaryStage.setScene(scene);
        primaryStage.setTitle(System.getProperty("java.version"));
        primaryStage.show();
    }
    
}

(note, I don't know which component might be the appropirate, please correct :-)
