I have merged the nested jar capability into the org.jboss.virtual tree, and to support this added a notion of an options map to the VFSContext. This is curretnly parsed from the rootURL query string. It could be made an explicit map of options that does not require a String key and value. I'm also working on the Serialization support, but the hiearchy in the abstract plugin classes is not consistent with the data that needs to be written out. The problem is that the AbstractVirtualFileHandler has the VFSContext reference, but it does not have the URL needed to recreate this. This exists in the AbstractURLHandler. Either the rootURL is needed at the AbstractVirtualFileHandler, or the handler url is pushed to this level, in which case I don't see much point to the AbstractURLHandler.
