JavaFX Hello World在开始时抛出java.net.ConnectException

我似乎遇到问题，为什么我不断收到这些java.net.ConnectExceptions。我使用干净的Java 7u6 x64安装来运行Windows 7。我关闭了防火墙（如果是这个问题）。我已经按照张贴在这里的解决方案：JavaFX Hello World在开始时抛出java.net.ConnectException

java.net.SocketException: Invalid argument: connect

但没有什么是摆脱这些问题。我甚至用Microsoft FixIt应用程序来重置我的IP堆栈。我还为环境变量JAVA_TOOL_OPTIONS变量添加了“-Djava.net.preferIPv4Stack = true”。没有任何工作。

这是来自Netbeans IDE的JavaFX“Hello World”程序。（在我的Mac上，我没有问题。）

任何帮助将非常感激！我不再确定在哪里寻找解决这个问题。最终的结果是每个JavaFX程序都需要很长时间才能运行。看起来它们都在等待套接字连接的超时，然后再继续使用该应用程序。 Java程序中不会出现这种情况，只有JavaFX。

下面是代码：

package anotherjavafxtest; 

import javafx.application.Application; 
import javafx.event.ActionEvent; 
import javafx.event.EventHandler; 
import javafx.scene.Scene; 
import javafx.scene.control.Button; 
import javafx.scene.layout.StackPane; 
import javafx.stage.Stage; 

/** 
* 
* @author redacted 
*/ 
public class AnotherJavaFXTest extends Application 
{ 

    @Override 
    public void start(Stage primaryStage) 
    { 
     Button btn = new Button(); 
     btn.setText("Say 'Hello World'"); 
     btn.setOnAction(new EventHandler<ActionEvent>() 
     { 
      @Override 
      public void handle(ActionEvent event) 
      { 
       System.out.println("Hello World!"); 
      } 
     }); 

     StackPane root = new StackPane(); 
     root.getChildren().add(btn); 

     Scene scene = new Scene(root, 300, 250); 

     primaryStage.setTitle("Hello World!"); 
     primaryStage.setScene(scene); 
     primaryStage.show(); 
    } 

    /** 
    * The main() method is ignored in correctly deployed JavaFX application. main() serves only as fallback in case the application can not be launched through deployment 
    * artifacts, e.g., in IDEs with limited FX support. NetBeans ignores main(). 
    * 
    * @param args the command line arguments 
    */ 
    public static void main(String[] args) 
    { 
     launch(args); 
    } 
}
