严重: Context [/struts2] startup failed due to previous errors
2010-8-25 10:22:09 org.apache.catalina.loader.WebappClassLoader clearThreadLocalMap
严重: A web application created a ThreadLocal with key of type [null] (value [com.opensymphony.xwork2.inject.ContainerImpl$10@3fa5ac]) and a value of type [java.lang.Object[]] (value [[Ljava.lang.Object;@95cfbe]) but failed to remove it when the web application was stopped. To prevent a memory leak, the ThreadLocal has been forcibly removed.

解决办法：是少了javassist-3.7.ga.jar，可以在struts2-2.2.1-all.zip包中找到。
