я получаю java.lang.ExceptionInInitializerError когда я пытаюсь инициализировать CategoryAxis XAxis

Question

Я пытаюсь добавить BarChart к существовавшему JPanel, но получает следующее сообщение об ошибке:

Я не уверен, что происходит, но я предполагаю, что причина проблемы заключается в том, что я пытаюсь добавить JFXpanel к JPanel:

521-->CategoryAxis xAxis = new CategoryAxis(); 
    NumberAxis yAxis = new NumberAxis(); 

    xAxis.setLabel("Threads"); 
    yAxis.setLabel("Time to msec"); 

    BarChart<String, Number> BC = new BarChart<String, Number>(xAxis, yAxis); 
    BC.setTitle("Time-Threads Compare"); 

    XYChart.Series series = new XYChart.Series(); 

    for (int i = 0; i < ThreadsNumOptions.size(); i++) { 
     for (int j = 0; j < Results.size(); j++) { 
      long sum = 0; 
      long times = 0; 

      if (ThreadsNumOptions.get(i).equals(Results.get(j).getMaxThreads())) { 
       times++; 
       sum += Results.get(j).getRawTime(); 
      } 

      if(times>0){ 
       series.getData().add(new XYChart.Data(ThreadsNumOptions.get(i)+" thread(s)",new TimeKeeper().GetTime((int) (sum/times)))); 
      } 
     } 
    } 

    Scene scene = new Scene(BC,300,225); 
    BC.getData().add(series); 

    final JFXPanel fxPanel = new JFXPanel(); 
    fxPanel.setScene(scene); 

    jPanelFX.add(fxPanel);

в идеале вы бы опубликовать Minimal, Complete, and Verifiable example.

Не видя этого источника, я не могу быть уверен, но это очень похоже на то, что вы пытаетесь инициализировать компоненты GUI JavaFX в потоке AWT.
