java.net.SocketException:无效的参数:连接

我的新笔记本电脑 (Alienware m17x) 在运行以下基本代码时抛出 java.net.SocketException: Invalid argument: connect:

My new laptop (Alienware m17x) throws a java.net.SocketException: Invalid argument: connect when I run the following basic code:

Server.java:

Server.java:

public static void main (String[] args) throws Exception {
        
    ServerSocket serverSocket = new ServerSocket (8888);
    Socket socket = serverSocket.accept();
}

Client.java:

Client.java:

public static void main (String[] args) throws Exception {
    Socket socket = new Socket ("localhost", 8888);
}

每次我运行 Client.java(在启动 Server.java 之后)我都会收到这个套接字异常.这是异常的完整跟踪:

Every time I run Client.java (after starting Server.java) I get this socket exception. Here's the full trace of the exception:

Exception in thread "main" java.net.SocketException: Invalid argument: connect
    at java.net.DualStackPlainSocketImpl.connect0(Native Method)
    at java.net.DualStackPlainSocketImpl.socketConnect(Unknown Source)

    at java.net.Socket.<init>(Unknown Source)
    at java.net.Socket.<init>(Unknown Source)
    at Client.main(Client.java:5)

我已经尝试了一些方法，但不幸的是总是抛出异常.这是我得出的结论:

I've tried a few things, but no luck the exception is always thrown. Here's what I have concluded:

• 更改端口号没有任何改变.
• 这不是网络问题.我在学校和家里都有例外.
• 我已经重新安装了 JVM 和 JDK，但没有成功.
• 这只发生在一台机器上.我在桌面上运行了相同的代码，但没有出现任何异常.我在两者上都使用 Windows 7.
• 它没有被防火墙阻止.我已关闭防火墙，但仍然存在此问题.

我应该怎么做或检查以解决此问题?

What should I do or check for to resolve this issue?

正如@PhilippeLM 和@beny23 让我意识到的那样，将 java 系统变量 java.net.preferIPv4Stack 设置为 true 解决了我的问题.但是我想要一个永久的修复.我不想每次运行java应用程序时都指定系统变量.

As @PhilippeLM and @beny23 made me realize, setting the java system variable java.net.preferIPv4Stack to true solves my problem. However I want a permanent fix. I don't want to specify the system variable every time I run a java application.

这是我再次尝试但没有成功的方法:

Here's what I've tried with no luck once again:

• 按照这些步骤
将我的机器首选项设置为首选 IPv4
• 将 java.net.preferIPv4Stack=true 行添加到 %JAVA_HOME%jrelib 中的 net.properties 文件中.

• Setting my machine preferences to prefer IPv4 by following these steps
• Adding the line java.net.preferIPv4Stack=true to the net.properties file in %JAVA_HOME%jrelib.

还有什么我可以尝试的吗?

Is there anything else I can try?
