CombinedVFSCache starts to fill the harddisk with copies of nested libraries from ear-deployment.

This happens only if the location of the deployment is not listed in permanentRoots.

We encounter this behavior by using the jmx-console to deploy the ear-file.

Space is stable for about 30mins. After that any request to the web application (JSF/Richfaces/Seam/EJB3/...) leads to a new copy of all nested libraries into the vfs-nested.tmp folder.
