在Apache Tomcat 7.0.42及更高版本上部署Mojarra 2.1.x和2.2会导致java.lang.UnsupportedOperationException

Question

我们的JSF Web应用程序基于java 7 se,JSF 2.1,使用Mojarra 2.1.27在Apache Tomcat 7.0.41及更低版本上运行良好.当我们尝试升级到Tomcat 7.0.42及更高版本时(我们已经尝试了每个版本高达7.0.50),在应用程序启动后,在第一次点击webapp中的任何URL时,我们在tomcat中看到以下错误日志:

我通过这个调试了,看起来Exception的来源是defaultFacesContext为null.

我用一个非常简单的应用程序重现了这个启动异常问题,只有一个静态JSF页面只有Hello World而没有支持bean,以及一个最小的web.xml,如下所示.在Tomcat 7.0.41上,一切都按预期工作,但总是会导致Tomcat 7.0.42+上出现以下错误.

只是想知道是否有其他人遇到过这个问题？

删除那个过时的监听器,然后放

<servlet>
    <servlet-name>Faces Servlet</servlet-name>
    <servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
    <servlet-name>Faces Servlet</servlet-name>
    <url-pattern>*.jsf</url-pattern>
</servlet-mapping>
