The log4j.xml is not being pulled into the war, so edits aren't being picked up.
here is a suggested fix for the log4j.xml issue in case it is helpful
Fixed in 170217.
Verified in dist built from SVN 170253.
Before the fix, I would use 'ant deploy-beehive build war' and then 'jar tf petstoreWeb.war | grep "log4j\."' I expected to see log4j.xml, but wouldn't see any files listed. With the latest build, I now see log4j.xml.
