Memory leak message with tomcat 7

[mic]

Hi all,

 

I am using Hermes 2.0 (version July 31, 2009) and it works fine with Tomcat 5 (version 5.5.27) and JDK 1.6.0_17. But after i migrate it to Tomcat 7, every time i shutdown the tomcat i got the following message in catalina.out.

 

Dec 19, 2012 1:18:10 PM org.apache.catalina.loader.WebappClassLoader checkThreadLocalMapForLeaks
SEVERE: The web application [/corvus] created a ThreadLocal with key of type [java.lang.ThreadLocal] (value [java.lang.ThreadLocal@10704e1]) and a value of type [com.sun.xml.messaging.saaj.util.transform.EfficientStreamingTransformer] (value [com.sun.xml.messaging.saaj.util.transform.EfficientStreamingTransformer@1d18084]) but failed to remove it when the web application was stopped. Threads are going to be renewed over time to try and avoid a probable memory leak.

 

Here lists the working environment.

 

Server version: Apache Tomcat/7.0.29
Server built:   Jul 3 2012 11:31:52
Server number:  7.0.29.0
OS Name:        SunOS

Does anyone know what the problem is? Thanks
