由于Java 7更新5我的Java Web Start应用程序请求建立连接的权限。 该应用程序与有效的证书签名。

一个弹出显示有以下文字：

该应用程序已请求允许建立www.example.com连接。 你想允许此操作？ [确定] [取消]

在拒绝请求我得到的控制台上跟踪：

该应用程序包含在获取从网站图片欢迎画面，该画面，然后开除，并出现主应用程序窗口。 欢迎屏幕出现之前只显示警告。 一旦应用程序启动尽管应用发起的多个连接不显示其他警告。

是什么原因造成这个问题？ 这是Java 7U5回归或新的功能？ 我还没有看到在这个任何参考发行说明 。

谢谢

Answer 1:

我们正在运行到这个问题，以及与安全弹出有时会造成死锁相结合。 （由于其他Webstart的错误）。 这很可能是由于从发行说明中7U5的“修复”为7177094。 我想，但是，你的bug＃7177349此评论，但它的评论是不可用的。
