java - JavaFX 2 slider labelFormatter not being used -

i have following code not label slider "foo50", etc... 1 expect setlabelformatter call, instead seems have no effect (the slider labelled 50, 100, etc , println's dont run). there missing? not implemented in default 2.2 skin? using oracle java 7

package javafxbugtest;  import javafx.application.application; import javafx.scene.*; import javafx.scene.control.*; import javafx.stage.*; import javafx.util.stringconverter;  public class javafxbugtest extends application {     @override     public void start(final stage primarystage)     {         slider cp = new slider();         cp.setlabelformatter(new stringconverter<double>() {              @override             public string tostring(double t)             {                 system.out.println("nope?");                 return "foo" + t.tostring();             }              @override             public double fromstring(string string)             {                 system.out.println("hey");                 throw new unsupportedoperationexception("not supported yet.");             }         });         cp.setmax(300);         cp.setmin(0);         cp.setshowticklabels(true);         cp.setshowtickmarks(true);         cp.setmajortickunit(50);         cp.setminortickcount(4);         cp.setvalue(152);         scene scene = new scene(cp);         primarystage.setscene(scene);         primarystage.show();     }      public static void main(string[] args)     {         launch(args);     } } 

slider label formatters not working in javafx 2.x (java 7) looks bug has been fixed in java 8:

rt-18448 [slider] label formatter not applicable.
