I'm using jitsi under Fedora 20 up to date.
Installed there is:
Starting jitsi from command line returns,
among other messages:
log4j:WARN No appenders could be found for logger (org.apache.http.impl.conn.BasicClientConnectionManager).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.
This with or without log4j installed.
I searched, and found out some email exchanges,
dated 2009, where it is mentioned that jitsi
uses java.util.logging and not log4j.
So, I was wondering where the warning come from.
Is there anything I need to install/configure
in order to remove it?
