tomcat 6.0.26
Description
Note, I believe these are only if you reload the application in tomcat which is not recommended. If you shut down the application these should not be a problem. Not sure though.
1.
SEVERE: A web application created a ThreadLocal with key of type [java.lang.InheritableThreadLocal] (value [java.lang.InheritableThreadLocal@49f5a659]) and a value of type [edu.internet2.middleware.grouper.j2ee.GrouperRequestWrapper] (value [edu.internet2.middleware.grouper.j2ee.GrouperRequestWrapper@70124154]) but failed to remove it when the web application was stopped. To prevent a memory leak, the ThreadLocal has been forcibly removed.
