> Using the hotdeploy feature of JBoss with struts enabled applications yields to 
> OutOfMemory-Exceptions. JBoss tries to undeploy the old application and 
> releases all references to it, but the allocated object are never garbage 
> collected. Since this happens with Jetty as well as with Tomcat I assume it's a 
> bug in Struts with cyclic references. 
>  
> Steps to reproduce: 
> 1) Install a vanilla JBoss 3.x 
> 2) Copy jakarta-struts-1.1-b2-blank.war into server/default/deploy 
> 3) Start JBoss 
> 4) Touch/copy server/default/deploy/jakarta-struts-1.1-b2-blank.war 
> 5) Wait a little bit to let JBoss finish the redeploy 
> 6) Go to step 4 
>  
> Under linux you can see with "ps -p <jboss.pid> -h -o rss" that the memory 
> usage is constantly increasing. With "lsof -p <jboss.pid> | grep 
> jakarta-struts-1.1-b2-blank.war" you can monitor references to the old 
> deployments.
