Description

After updating to MyFaces 1.2.10 I still see following error in Tomcat log after stopping my web app:

26.05.2011 12:33:54 org.apache.catalina.loader.WebappClassLoader clearThreadLocalMap
SCHWERWIEGEND: The web application [/fliti] created a ThreadLocal with key of type [org.apache.myfaces.el.convert.VariableResolverToELResolver$1] (value [org.apache.myfaces.el.convert.VariableResolverToELResolver$1@5c3bb813]) and a value of type [java.util.HashSet] (value [[]]) but failed to remove it when the web application was stopped. This is very likely to create a memory leak.

I thought this was solved with bug MYFACES-3001"Memory Leak in MyFaces 1.2 related to RuntimeConfig ThreadLocal"
but apparently only the issue with org.apache.myfaces.config.RuntimeConfig has been fixed.
