This should be:
org.apache.avalon.framework.logger.Logger avlog =
new org.apache.avalon.framework.logger.LogKitLogger(log);
MessageHandler.setScreenLogger(avlog); //<-- missing!!!
driver.setLogger(avlog);

I quickly copied your LogKit setup code to a test class (attached) and
tried it. Worked fine. You sure you're looking at the right file? Your
logfile lands in the "current" directory whereever that is. Try
switching to the ConsoleLogger to see if there's log output at all.
