> I'm chasing down some Geronimo memory leaks when deploying/undeploying the DayTrader sample application. 
> One memory leak I see is caused by o.a.a.utils.JavaUtils.enumMap. JavaUtils is loaded by a parent ClassLoader but is has strong references to classes (the keys of enumMap) which were loaded by child ClassLoaders. This prevents the ClassLoader, and the classes it has loaded, from being GC'ed. This means we'll eventually run out of PermGen memory...
> I converted enumMap to be a WeakHashMap and I now see the ClassLoaders being GC'ed. I didn't download using cvs. So, I don't have a patch. I'm happy to generate one, if you'd like...
