struts2+tomcat 重新部署问题

[我是个老手哈哈]

严重: The web application [/*****] created a ThreadLocal with key of type [com.opensymphony.xwork2.inject.ContainerImpl$10] (value [com.opensymphony.xwork2.inject.ContainerImpl$10@2e5facbd]) and a value of type [java.lang.Object[]] (value [[Ljava.lang.Object;@b45c414]) but failed to remove it when the web application was stopped. This is very likely to create a memory leak.
最近总是报这样的错误，
请大神帮一下忙!!!
