logging problem (bug?)

[ma...@colinx.com]

I am running tomcat 5.5 on a java 1.5 vm.
I want to turn tomcat logging (via java.util logging) up for debugging but 
if I set everything to FINEST there is so much logging that It takes far 
too much time to start up.  I am trying to trim down some of the excess 
logging to make this more manageable.  One of the packages producing 
excessive logs is org.apache.tomcat.util.digester.  I am trying to turn 
this package down, but found that I cannot affect it by turning down the 
logger of that name with the following line in 
$JAVA_HOME/jre/lib/logging.properties: 

org.apache.tomcat.util.digester.level = INFO

Rather, the only logger I have found that affects it is 
org.apache.commons.  The problem is that this then blocks all of the 
commons logging which I want.  Is there a way that I can just turn down 
the logging on the tomcat.util.digester package?  Is this a bug?
