There has been some work on the Logger.debug(Object)** signature problem on 
log4j-dev. In a fortunate ans somewhat ironic twist of events, log4j may 
end up providing better support for SLF4J than NLOG4J whose raison d'etre 
is SLF4J compliance.

If the Logger.debug(Object) signature is too much of a hurdle for you, 
please shout so that it can be fixed in a future version of NLOG4J or 
hopefully in log4j itself.

** I assume that maven-cobertura-plugin 1.1 is complaining about the 
missing Logger.debug(Object) method.

No. There are no provisions in the SLF4J API to allow configuration.

Interesting question. Have you considered casting the returned Logger instance?
