我有一个在Tomcat 6上运行良好的应用程序。我现在已将该应用程序移至Tomcat 7，并且JSP抛出了编译异常以下的错误。

我查看了jasper为两个tomcat版本创建的java文件，发现了一个重大更改。例如，与行号错误相对应。22，tomcat 6的java文件中的getDependants（）方法具有以下签名：
public Object getDependants() { return _jspx_dependants; }
而对于Tomcat 7，这是
public java.util.Map<java.lang.String,java.lang.Long> getDependants() { return _jspx_dependants; }
我几个月前也提出了这个问题。找不到解决方案，所以我切换到了tomcat，但是现在我们需要在tomcat 7上对此代码进行生产发布，因此需要针对此的具体解决方案。
如果有人可以帮助我确定解决该问题所需的纠正方法，那将是很好的

终于找到了冲突的jar。它是org.osgi.foundation-1.2.0.jar。但是，我正在使用的另一个依赖项需要此jar，因此需要找到一种解决此问题的方法。
