> This map continues to have reference to classes generated and used by the now undeployed webapp meaning the webapp classloader never goes  away. 
> The implementation of this map although weak is not weak enough,  because if a entry references a key (it seems to) then the key although it is a WeakReference never goes away and therefore neither does the entry (the classloader). 
> See the "implementation note" 2/3 of the way through the javadoc here: http://java.sun.com/j2se/1.5.0/docs/api/java/util/WeakHashMap.html
