Sorry if this isn't quite the correct place for this comment (I can try to report a new issue if you like).
In this report you can see that the BundleException was reported at the INFO level. I think that actually Felix tries to report this at the WARNING level, but for some reason it cannot find the OSGi LogService and will thus presumably report the issue using System.out which is then by Glassfish redirected to the server.log at the INFO level.
I think serious problems like this really need to be logged at the WARNING level. Can anyone comment on this?
