log4j prints out messages during init

           Summary: log4j prints out messages during init
           Product: Log4j
           Version: 1.3alpha
          Platform: All
        OS/Version: Linux
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: Other
        AssignedTo: log4j-dev <at> jakarta.apache.org
        ReportedBy: thomas.hiller <at> hp.com

The new log4j (HEAD) prints out initialisation messages:
**Start of LogManager static initializer
*** 
configurationOptionStr=file:/data/home/thiller/Projects/ADAM/client/target/inst
aller/adam-client-3.00-dev/bin/../conf/log4j.adam
log4j:INFO Using URL 
[file:/data/home/thiller/Projects/ADAM/client/target/installer/adam-client-
3.00-dev/bin/../conf/log4j.adam] for automatic log4j configuration of 
repository named [default].
** End of LogManager static initializer

How can these messages be suppressed ?
I have an application, where normal console output is very strict (the log4j 
messages are interpreted as an application error).
