Jsf javax.faces.context.FacesContext.getExceptionHandler中的java.lang.UnsupportedOperationException

我正在尝试将运行在JBossAS5.1.0上的现有JSF2.1应用程序迁移到JBossEAP6.4。我在JBoss-deployment-structure.xml中添加了JBoss AS 5.1.0中的Mojarra JAR，以及所有其他必需的JAR作为模块依赖项。 当我尝试启动Jboss EAP（standalone.bat）时。我正在日志中打印以下内容：

java.lang.UnsupportedOperationException 位于javax.faces.context.FacesContext.getExceptionHandler

完整堆栈跟踪如下所示：

我错过了什么？请帮助

此异常表明存在多个不同版本的JSF库的类路径污染。清理并确保只提供一个（请记住，JBoss默认情况下已经提供了自己的JSF库）。我已经从WEB-INF/lib文件夹中删除了JSF-impl.jar和JSF-api.jar，并在JBoss-deployment-structure.xml中添加了依赖项。还是不走运！：（或者你建议在我的war文件的WEB-INF/lib中添加JAR，并在我的Jboss deployment structure.xml中为Jboss模块添加排除项吗？如果你的代码使用的是旧的JSF JAR，那么是的，在WEB-INF/lib中添加JAR，并在Jboss-deployment-structure.xml中添加排除项。Jboss EAP 6.4将包括最新的JSF JAR，我假设你会这样做。）我不想要。
