Log.setLogger(new StdErrLog()); or Log.setLogger(new Slf4jLog()); or Log.setLogger(new JavaUtilLog()); http://download.eclipse.org/jetty/stable-7/apidocs/org/eclipse/jetty/util/log/package-summary.html -- Joakim Erdfelt <[email protected]> On Fri, Sep 28, 2012 at 8:04 AM, ceposta <[email protected]> wrote: > Any committers can help me understand how this could happen?
