Subject Memory leak with ThreadGroups
Date Thu, 23 Jan 2003 21:58:28 GMT
One of my classes creates a static ThreadGroup.  I notice that when I update a class and 
tomcat reloads that context the ThreadGroup is still around. If the ThreadGroup is still 
around that means the old class is still around, which means that class loader is still 
around.  Why is it still around?  I tried making the ThreadGroup daemon but it didn't help.

I think the fact that the old class loaders are still around goes a long way to explaining

why tomcat takes up so much memory.
