Hi Arnaud,

I think that it should be possible to deploy the pax-logging bundle in
JBoss AS7, even though AS7 provides logging (Log4j, SLF4J, Commons
Logging, JBoss Logging) out of the box. Could you please file a bug
here: https://issues.jboss.org/browse/JBOSGi with some instructions on
how to reproduce?

Thanks,

David
