ThreadLocal leak with Weld Servlet

Nov 22, 2010 7:13:40 PM org.apache.catalina.loader.WebappClassLoader clearThreadLocalMap
SEVERE: The web application [/active1] created a ThreadLocal with key of type [null] (value [org.jboss.weld.injection.CurrentInjectionPoint$1@30b95f2]) 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.

Weld Servlet 1.1.0-SNAPSHOT / Beta2 / Beta1 on Tomcat 6

Not sure if this is Weld Servlet or Weld Core.
