java - 更新 Java 导致小程序停止工作 - 未找到 testJava2_1/TestVMApplet.class

Question

嘿，

在 Windows 7-64 位上将 java 版本从 6u31 更新到 7u4 后，小程序停止工作。我使用java-32位，浏览器也是32位(尝试过IE9和Firefox 12.0)，唯一的原因是更新了java.lang. 我使用了 http://www.java.com/en/download/testjava.jsp 中的测试，得到的结果是:

我已经尝试了很多不同的替代方案，例如禁用防火墙、在 Java 控制面板上禁用下一代插件、清除缓存、卸载并重新安装(JRE 和 JDK)、使用混合模式安全验证，也许还有一些我不记得了。 我不知道我还能尝试什么来让它发挥作用。有人经历过同样的事情并解决了吗？

啊，根据公司政策，由于安全更新，我们必须尽可能坚持使用最新版本。

好的，问题是我在使用 java 访问页面时连接了 VPN (CISCO)。从 Java 7 开始，由于 Ipv6 存在问题 (http://jonathangiles.net/blog/?p=1126)。因此，我从 VPN 连接中禁用了它，并将这一行添加到 java 运行时参数中: -Djava.net.preferIPv4Stack=true

现在一切正常。
