log4cxx: No level could be found named "null".

[Jitendra Kharche <Ji...@geometricsoftware.com>]

I am getting the following error
 
log4cxx: No level could be found named "null".
 
What could be the reason. The log4cxx.xml file has following
configuration.
 
 
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE log4j:configuration SYSTEM "./log4j.dtd">

I believe this would occur in log4cxx 0.9.7 when logging was being  
attempted in a static constructor.  In some cases, the static  
constructor that requested the logging would be called before the  
static constructor that initialized Level::INFO and similar.

If it is occurring in the current SVN HEAD, then please let us know  
what compiler and platform that you are seeing this occur in and if  
you could provide a sample app that demonstrates the behavior even  
better.  To work around the problem, try replacing use of Level::INFO  
with Level::getInfo().
