Question

我已经检查了其他stackoverflow答案，但是它们都没有针对JSF facescontext的答案，因此我不得不提出一个问题。我们有jdk 6，jsf 1.2和mySQL 5.5，现在我们已升级到Java 8和mySQL 5.7。为此，我将mySql-connector jar从3.1.11替换为5.1.18。但是当我启动tomcat时，它会引发如下异常：

深入研究代码，我发现内部错误方法FacesContext.getCurrentInstance();中的代码正在错误。当我检查相应的jar时，它指向 jsf-api.jar。。现在我知道一种解决方案是在VM中添加 -noverify 参数，但是，可能是查看我的生产环境的补丁程序，我无法弄清楚根本原因是什么，可以采取什么解决方案？

Answer 1

找到正确的论点：实际上，我尝试从安全模式将 webdir 添加到环境变量中，但是它也不起作用。所以我删除了它，并在tomcat的参数中添加了 -Xverify：none ，它开始起作用。

FacesContext.getCurrentInstance（）引发java.lang.VerifyError：分支目标异常时堆栈图框架不一致
