Do you use the POI SMX bundle or do you wrap POI as private of your
package ?

As you can see from the stacktrace, the call to the DefaultLogBuilder is
made from Apache POI.
Does this mean that Apache Poi can not be used in Karaf?

Hi Richard,
Yes and no ;)
Pax Logging "wrap" log4j classes, mostly the API, but not all classes,
especially the one that could not work in OSGi or don't make sense with
Pax Logging.
Especially, in pax-logging-api, all org.apache.logging.log4j.internal
classes (including DefaultLogBuilder) are not shipped as you are not
supposed to use it (it's delegated to Pax Logging service).
Regards
