The 'details I left out' are much too voluminous until and unless I boil this down to a test case. In brief, I agree, it makes no sense. I run the program in equinox, it works. I run it in felix, it fails. Maybe my code is wrong and equinox excuses it for some reason. Maybe something else. I apologize for using bandwidth on such a muddle. > > If you go back to equinox, you might try registering your log service with > service ranking > 0; that might make it preferred vs the built in equinox one. Unfortunately, I'd have to fork: https://github.com/qos-ch/slf4j/blob/master/osgi-over-slf4j/src/main/java/org/slf4j/osgi/logservice/impl/Activator.java But I just figured out how to get the equinox log where I can see it, maybe. > > david jencks > >> On Aug 11, 2016, at 1:36 PM, Benson Margulies <ben...@basistech.com> wrote: >> >> Quite some time ago, we had a requirement to have read-only >> provisioned OSGi caches.
