I wrote an own java.util.logging.Handler to get the logs over the network. =
The handler is configured via "myWebapp/WEB-INF/classes/logging.properties"=
 and is working very well. The handler uses some threads to do his job. I u=
sed the close()-Method to interrupt them. But when shutting tomcat down or =
doing an undeploy I always get messages like this:

-------
23.08.2010 23:43:14 org.apache.catalina.loader.WebappClassLoader clearRefer=
encesThreadsSEVERE: The web application [/testWebapp] appears to have start=
ed a thread named [Thread-2] but has failed to stop it. This is very likely=
 to create a memory leak.
23.08.2010 23:43:14 org.apache.catalina.loader.WebappClassLoader clearRefer=
encesThreadsSEVERE: The web application [/testWebapp] appears to have start=
ed a thread named [Thread-2] but has failed to stop it. This is very likely=
 to create a memory leak.
-------

Theses threads were started by the handler and can not be stopped by tomcat=
. Interestingly the cose()-Methode of my handler - where the handler would =
kill these threads - gets called after theses messages...

I don't really know how to understand these messages? Why are theses messag=
es produced before calling the close() Method of the handler?

Thanks a lot!
