This indeed should not happen as this would break sun specs. I would be quite
surprised it it was at all possible :/
How did you conclude the webappclassloader is sharing the class between
webapps in your case?
Are you sure you are not mistakenly using a shared class?
Not only does every webapp
Its hard to tell - you need to tell us more - e.g. what version of
Tomcat are you using.
I have gotten similar messages when I used the deployer app to undeploy

I suppose Tomcat shouldn't probably do an indiscriminate flushCaches().
It would probably have to selectively clear only the cache entries for

See my other message for the reasoning. I would recommend not to use

This has to do with Log4j. Make sure you set up a servlet context listener
