My guess is you&#39;re not seeing the actual inclusion of the commons-logging.jar, but the API&#39;s included in that jar.  Those API&#39;s are replicated by the jcl-over-slf4j.jar file but use the SLF4j API under the covers.  If you want to make sure people can&#39;t write to that API, remove that jar file.<div>
