The ThreadLocalLeakPreventionListener was added recently to tomcat. It is available in tomcat 7 as well as the latest version(s) of tomcat 6. Make sure you have the latest tomcat 6, with a clean installation (your installation might have the server. Xml from the new version and the jars from the older one).
