I've committed the inital cut at the VFSClassLoaderPolicy http://jira.jboss.com/jira/browse/JBOSGI-14 It's likely the final version will be more integrated with the VDF's classpath structure information rather than directly taking VFS urls, but at least the current class shows how to integrate the VFS with the new classloader. With this class done, we pretty much have all the functionality of the UnifiedClassLoader using the VFS. With OSGi style rules as well. Although it would need a subclass of this class http://jira.jboss.com/jira/browse/JBOSGI-15 to allow much of the policy to be set. JBOSGI-15 will almost certainly include more fine grained filtering like the MockClassLoaderPolicy in the classloader tests. e.g. excluding individual classes (not just from what is exported/imported but what the classloader itself can see in the "private" classes).
