我在JavaFX文件中编写了一些代码。现在，我得到这个错误码：这是什么IllegalStateExeption？
Exception in thread "usb4java IRP Queue Processor" java.lang.IllegalStateException: Not on FX application thread; currentThread = usb4java IRP Queue Processor

BUILD停止（总时间41秒），
我不知道如何处理这个疑难问题知道，它与一个线程的问题（我认为） ，但我不知道什么是真的错了，或者这个异常会对我说什么...... 下面是一些代码：
public class UsbDataInputListener implements UsbPipeListener {

throw new UnsupportedOperationException("Not supported yet."); //To change body of generated methods, choose Tools | Templates.
}

public void dataEventOccurred(UsbPipeDataEvent upde) {
final byte[] recData = upde.getData(); //Übertragene Bytes
//Input wird überprüft
//Aktion für die jeweilige Taste wird durchgeführt
if(Arrays.equals(recData, Keys.POWER)){
try {
System.out.println("Power of pressed ...");
ShutdownInfoController isc = new ShutdownInfoController();
Window shtdnWin = new Window("/app/view/ShutdownInfoView.fxml","Info zum Herunterfahren",

任何一个想法有什么不对？
