JavaFX Hello World在開始時拋出java.net.ConnectException

我似乎遇到問題，爲什麼我不斷收到這些java.net.ConnectExceptions。我使用乾淨的Java 7u6 x64安裝來運行Windows 7。我關閉了防火牆（如果是這個問題）。我已經按照張貼在這裏的解決方案：JavaFX Hello World在開始時拋出java.net.ConnectException

java.net.SocketException: Invalid argument: connect

但沒有什麼是擺脫這些問題。我甚至用Microsoft FixIt應用程序來重置我的IP堆棧。我還爲環境變量JAVA_TOOL_OPTIONS變量添加了「-Djava.net.preferIPv4Stack = true」。沒有任何工作。

這是來自Netbeans IDE的JavaFX「Hello World」程序。（在我的Mac上，我沒有問題。）

任何幫助將非常感激！我不再確定在哪裏尋找解決這個問題。最終的結果是每個JavaFX程序都需要很長時間才能運行。看起來它們都在等待套接字連接的超時，然後再繼續使用該應用程序。 Java程序中不會出現這種情況，只有JavaFX。

下面是代碼：

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); 
    } 
}
