Nelson MELINA commented on LOG4J2-703:
--------------------------------------

Ok guys, it seems it is working. I still have trouble figuring where to place log4j2.xml so
that it is used as a configuration by my main goal of verifying that it could be used in an
Android apk is achieved.

THanks for the help.
