I attached a patch for Solr 1.4.1 release on https://issues.apache.org/jira/browse/SOLR-1902 that made things work for me. This strange behaviour for me was due to the fact that I copied the patched jars and war inside the dist directory but forgot to update the war inside the example/webapps directory (that is inside Jetty). Hope this helps. Tommaso
