我正在使用一些专有的应用服务器（用于SIP协议），我们使用嵌入式tomcat（用于HTTP协议）。我们用java 1.6u21运行它。
现在我想使用java 1.7u51，所以我编译了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app时，java.lang.IllegalAccessError就出现了。但就我而言，我已经在java1.7u51上编译并运行了应用程序。
我想知道为什么会遇到这个问题。
仅供参考......我正在使用嵌入式tomcat 7。
答案 0 :(得分：0)
它看起来更像是一个jar版本的问题。如果您正在使用任何第三方jar，请确保正确的版本在类路径中并重新编译整个应用程序并检查它
