Jetty maven插件无法热重新部署shiro筛选器

我不确定这是jetty的问题还是shiro的问题，但我正在尝试使用jetty Maven插件进行开发，我想要的一个关键特性是jetty在文件更改时的热重新部署。然而，当jetty试图重新加载应用程序时，Shiro抛出了以下异常，我不确定如何纠正这一点

最后，这里是我的maven pom文件的相关部分：

编辑：另一条相关信息。我正在eclipse中编辑文件，并使用M2E Maven集成eclipse插件。这可能与eclipse和/或该插件如何重新编译文件有关。

我改用jetty 8而不是jetty 9候选版本，问题就解决了。注意：我也在9.0.1.v20130408上试用过，但在该版本中也不起作用。问题似乎是ServletContextListeners在jetty 9的重新加载过程中没有重新初始化。
