In org.ops4j.pax.logging.service.internal.JdkHandler.publish method, there's a TODO comment like
// TODO: Can't associate a bundle with the JDK logger. So how??
the pax-logging org.ops4j.pax.logging.service.internal.JdkHandler can't associate a bundle with the JDK logger, so any bundle which use java.util.logging.Logger, can't get bundle infos in pax-logging, that's why we can't see bundle specific info(bundle name, id, version) from log if the bundle use java.util.logging.Logger, but it's OK when use other Loggers.
