Java:wicket找不到组件

试图重新打包由另一个开发人员维护的东西，并遇到wicket组件问题。老实说，只是在寻找一个正确的方向来缩小这里实际发生的事情。我没有访问的源代码，只有编译战争，我已经反编译。这似乎是在他们完美的环境中运行时可以正常运行的，但我需要运行稍微不同的java版本

从这个错误看来，它就是找不到“特征”组件。我怎样才能追溯这个？反编译ServerStatusPage的类时，我只看到“features”作为变量。现在有没有一种快速的方法可以删除状态页面中有问题的区域并重新打包war文件？当我尝试时，我遇到了更多的问题，说我排除了应该存在的组件

运行时的完整错误如下所示：
