log4j log message during log4j initialization

Question

Hello,

I was trying to setup log4j (xml based) configuration, Use LevelRangeFilter, as described in the official site. Everything is fine so far, except log4j spit out its own log messages till it initializes. After the 'finished configuration' line, everything is normal. Also, there is an error stating "log4j: Could not find root logger information. Is this OK?" .

thanks.

log4j: reset attribute= "false".
log4j: Threshold ="null".
log4j: Level value for root is  [all].
log4j: root level set to ALL
