There are two RollingFileAppender's in log4j 1.3.x.   
org.apache.log4j.RollingFileAppender (o.a.l.RFA or log4j 1.2 RFA) and  
org.apache.log4j.rolling.RollingFileAppender (o.a.l.r.RFA or log4j  
1.3 RFA).  o.a.l.RFA was originally not in the log4j 1.3 development  
has been added back for compatibility.  In 1.3.8, it was a proxy for  
o.a.l.r.RFA which would allow log4j 1.2 configuration files to  
continue to work.  But since then the log4j 1.2 RFA has been ported  
into log4j 1.3 so that extensions of the log4j 1.2 RFA would continue  
to work.

If you are wanting to extend the new o.a.l.r.RFA, you would want to  
provide a new RollingPolicy which would open encrypted files.   
o.a.l.r.RFA is marked as final since it is intended to be extended by  
users providing custom RollingPolicy and TriggeringPolicy.

If you are wanting to extend the old o.a.l.RFA, you can get the  
source from SVN.
