项目在redeploy时出现以下异常：

2014-1-2 17:22:46 org.apache.catalina.loader.WebappClassLoader clearThreadLocalMap

严重: The web application [/XinRui02] created a ThreadLocal with key of type [com.opensymphony.xwork2.inject.ContainerImpl$10] (value [com.opensymphony.xwork2.inject.ContainerImpl$10@152bdc7]) and a value of type [java.lang.Object[]] (value [[Ljava.lang.Object;@1296d1d]) but failed to remove it when the web application was stopped. This is very likely to create a memory leak.

通过google，找到以下的贴子：

看到下面的回帖说的有几分道理：

换了tomcat之后，果然警告不在出现。

特此mark，向22楼致敬！
