Hi, i experienced strange lucene plugin behaviour. if i don't set the log4j.logger.net.jkraemer.xwiki=debug line into my log4j.properties file i get a null pointer exception after posting the search from. If the line is set to "debug" it works properly. Does also not work "error" or "warn". - Can't find problems in the logfile! Any suggestions? Thank you! Sascha Oesterle
