java - 应用程序从 java 6 迁移到 java 7

Question

我正在使用一些专有的应用程序服务器(用于SIP协议(protocol))，其中我们使用嵌入式tomcat(用于HTTP协议(protocol))。我们使用 java 1.6u21 运行它。

现在我想使用java 1.7u51，所以我已经编译了java1.7u51上的所有代码。当我启动服务器时，我收到以下错误:

我在网上搜索发现，当我们在 diff java 版本上编译 src 并在不同版本上运行应用程序时，就会出现 java.lang.IllegalAccessError 。但就我而言，我已经在 java1.7u51 上编译并运行了应用程序。

有什么想法为什么我会遇到这个问题。

仅供引用...我正在使用嵌入式 tomcat 7。

看起来更像是 jar 版本问题。如果您使用任何第三方 jar，请确保正确的版本位于类路径中，并再次重新编译整个应用程序并检查它
