从上面的错误信息中，我们可以看出，出现了循环引用，org.apache.commons.httpclient.HttpException->org.apache.commons.httpclient.URIException->org.apache.commons.httpclient.HttpException，最后导致堆栈溢出

查看项目，发现org.apache.commons.httpclient.HttpException这个类同时在两个架包中存在，分别是

jbossall-client.jar和commons-httpclient-3.0.jar

所以，我们需要去掉一个架包，然后重启，tomcat就可以正常启动了。
