我刚刚将我的计算机（Windows 8、Windows 7 和 OS X Mountain Lion）升级到 Java 7 update 45，我的 Java 小程序不再工作了。我在控制台中收到以下异常：

我不明白为什么这已经停止工作。显然有一些安全更新已经破坏了它，但我看不到它是什么。所有 jar 都使用相同的 Thawte 证书进行签名。清单文件都包含“Trusted-Library: true”和“Permissions: all-permissions”属性。我也尝试了 codebase 属性，但什么也没做。我已经阅读了更新 45 发行说明，但看不到任何会导致这种行为的东西，但显然我遗漏了一些东西。任何人都可以帮忙吗？
