No Hot Redeployments

My application does not do any hot deployments but I am seeing  the behavior 
often associated with classloaders not being garbage collected on hot deploy.   
(http://forum.java.sun.com/thread.jspa?threadID=492509&messageID=2317057 ) 

Any HttpRequest, even the very first one after server startup, will 
consistently create at least 3 uncollectable DelegatingClassLoaders.  A single 
user was able to create 113 of these chewing up 49K of RAM in just a couple of 
minutes.  Are others seeing this?  I found it while looking into a massive 
memory leak that exists at some customers but not others.  

I investigated the relationship between the ClassNotFound issue fixed in 4.0.4 
(http://jira.jboss.com/jira/browse/JBAS-3041)and the behavior I am seeing.  I 
breakpointed ClassNotFoundException's constructors but this proved not useful 
due to extensive creation of these by BootstrapClassLoader.   Does anyone know 
if this bug above only occurs when the class is not found by any ClassLoader or 
if it can occur for any ClassNotFoundException?  I am unable to locate a case 
where my code silently catches ClassNotFoundException and I am not using a an 
MVC framework.

Any guidance would be much appreciated.
