This is some fault infomation when shutdown tomcat

2010-10-9 22:07:32 org.apache.catalina.loader.WebappClassLoader clearThreadLocalMap
fault:The web application [/testWeld] created a ThreadLocal with key of type [null] (value [org.jboss.weld.injection.CurrentInjectionPoint$1@25927ae]) and a value of type [java.util.Stack] (value [[]]) but failed to remove it when the web application was stopped. This is very likely to create a memory leak.

I test on tomcat 7

I notice that each weld request excute by each tomcat Daemon Thread [http-8080-exec-xx] managed by tomcat ThreadPoolExecutor.
So request ThreadLocal variable should cleanup at the end of rereqst?
There are 20 fault when stop tomcat and tomcat ThreadPool size is 10.If i increase to 20 there are 40 fault.
