Log4j 1.x will not work in Java 9, need to migrate to 2.x
Hello guys, I noticed in Karaf 4.0.5, Log4j 1.x is still being used as the
logging framework. This is no longer supported in Java 9 due to being end
of life and a bug involving the JDK version number string having changed
format significantly.
Are there plans to make Log4j 2.x the default in Karaf 4.1 or 5.0? If not,
I can help you guys migrate. We're keeping track of migration efforts in
this issue: https://issues.apache.org/jira/browse/LOG4J2-1473

I mean old config files written for log4j should work in log4j2. Log4j 2
already has a properties file syntax, but it's different from the old 1.x
format.

Fwiw, pax-logging-log4j2 is the backend for Karaf 4.1.
And we already support log4j configuration style
(though prepended with log4j2 instead of log4j).

As a quick followup, we're working on supporting log4j 1.x configuration
files in 2.x lately, so eventually we should be able to switch the default
backend (or at least the default used in Karaf 4.1).

Hi Matt,
we're not directly using Log4j 1.x it's used by Pax-Logging which itself
brings along a lot of needed stuff.
So to fullfill what you are requesting we would need to replace Pax-Logging
by Log4j2 and therefore require a lot
of changes to stuff that has been working with Pax-Logging as Pax-Logging
provides all kinds of APIs with only one implementation which is log4j 1
right now. But you can also use log4j 2 as alternate backend.
regards, Achim
