How to achieve anti aliasing in javaFX ? I have applied some tricks... but it didn't work

Question

after reading the question it looks like I have asked the question which was already asked but believe me I have tried the possible solutions where in I didn't get the desired output....

First of all What I want to achieve ?

To achieve the AntiAliasing , I have tried some of the way like

1. new Scene(,,,,SceneAntialiasing.BALANCED);
2. shape[object].setSmooth(true);
3. System.setProperty("prism.lcdtext", "false"); from the link How to force anti-aliasing in JavaFX fonts?
4. I have tried to use SubScene as well , but it was somewhat improper way to go...

But none of the above solutions works for me ... So Now, I am posting the SSCVE ...

Please help me on this ...

Thanks in advance...

the CreateScene method in UI class which  extends JFXPanel looks like ....  

private Scene createScene() 
{  

    Group rootNode = new Group();
    //System.setProperty("prism.lcdtext", "false");
    double StrokeWidth = 1.0;
    double yPosition = 20.0;
    //textFontsize = textFontsize + 0.7 ;

    // straight Vertical Lines

            rootNode.getChildren().add(createLines(35.0, yPosition+20, 35.0, yPosition+150, StrokeWidth,"GREEN"));
            rootNode.getChildren().add(createLines(25.0, yPosition+20, 25, yPosition+150, StrokeWidth,"BLACK"));
            rootNode.getChildren().add(createLines(30.0, yPosition+20, 30, yPosition+150, StrokeWidth,"BLUE"));

            // straight horizontal lines

            rootNode.getChildren().add(createLines(80.0, yPosition+30, 240, yPosition+30, StrokeWidth,"RED"));
            rootNode.getChildren().add(createLines(80.0, yPosition+40, 240, yPosition+40, StrokeWidth,"GREEN"));
            rootNode.getChildren().add(createLines(80.0, yPosition+50, 240, yPosition+50, StrokeWidth,"BLACK"));

            // create slope lines 

            rootNode.getChildren().add(createLines(420.0, yPosition+20, 470, yPosition+150, StrokeWidth,"BLACK"));
