Generally when you get this kind of error with Solr, it means you have a mix of old and new jars. This might be from an upgrade, where either the old war expansion doesn't get removed, or from unnecessarily including jars on your classpath. If you are using custom code or a code patch, it probably needs changing for a new Solr version. Thanks, Shawn
