java.lang.VerifyError/java.lang.J9VMInternals.verifiyImpl处的堆栈下溢错误

我正在尝试将基于struts的Java 6应用程序从Websphere 6.1中运行良好的应用程序升级到Websphere 8.5。到目前为止，尚未对代码进行任何更改。但这一个让我很反感。我得到如下验证错误/堆栈下溢错误：

在上面日志的第8行，它指向我的UrlGateway类中的第71行，该行除了从请求中获取参数并转发到index.jsp之外，什么都不做。我班的第71行如下：

application.getRequestDispatcher(forwardPath).forward(request,response);//application is instance of ServletContext

有没有关于如何解决这个问题的想法？这是由于Websphere 8.5中的潜在错误造成的吗？

-谢谢。

这是WS 8.5中的错误，您需要更新，请参见此处：

或者这是代码覆盖率问题，您需要禁用它，如此处所述：
