Hello, I've just checked also the patch available on the XStream project (https://jira.codehaus.org/browse/XSTR-566) and it fails also. Actually, we were waiting for a fix from the xstream team. It can take some time. I've updated our issue with your comment: http://restlet.tigris.org/issues/show_bug.cgi?id=863
