Hi, the user documentation still refers to configuring logging using log4j(1) while Karaf has moved on to log4j2. I started updating the documentation but did not feel confident changing anything from the "Advanced configuration" stage towards the bottom of the documentation. The changes I made up to that point are available at https://github.com/NetNow/karaf/commit/e0a592117bb259833f8500c6c534c2f1deb13d22 in case they are of use; but if that commit were applied as-is, the manual would have instructions for both log4j and log4j2 configuration in it which is possibly worse than now.
By the way, the file etc/org.ops4j.pax.logging.cfg has a few log4j(1) properties left in but commented out at the bottom. Regards, Arunan
