java.lang.NoClassDefFoundError：无法初始化类sun.security.ec.SunEC（在最近的JRE更新后发生）

最新的JRE（1.7.0_25）更新后，我的应用程序将不会像以前那样从webstart启动 . 我没有部署任何较新的jar文件或更改了Web服务器上的JNLP文件，但我无法从webstart启动该应用程序 . 它可以从IDE运行，也可以从本地jar执行

我试图在控制面板的高级选项卡中禁用所有证书检查等，但错误仍然存在，我不确定这是否与最新JRE中的新安全设置有关，或者是否有其他更改（可能在网络上）服务器？）我不控制Web服务器我只有一个发布应用程序的页面，并且可以访问jar文件的驱动器位置，权限对于驱动器位置是正确的 . 我现在迷失了什么问题是！我试着辞去 jar 并验证签名

我感谢民间所能给予的任何帮助！完整错误如下：
