Brian Leathem commented on RF-12601:
------------------------------------

Can you try using the jvisualvm tool shipped with the JDK to identify what class is not being garbage collected on re-deploy?  This will help us determine if the issue is a RichFaces issue, a tomcat issue, or a Xerces issue.

> I created a simple web app without any classes, xhtml files, config files.
> There are only some jars, including xerces, in the lib folder only.
> A "java.lang.OutOfMemoryError: PermGen space" occurs if this app is started, stopped and restarted.
> It does not occur if either richfaces-components-XXX hars OR xerces are removed from the webApp,
