---------------------------------------------------------------------
I do not agree. This causes much more trouble than it should. I propose we
follow the example of bndtools and simply ignore require capability headers of
type service. We have lots of issues with it in our TESB product alone. Once
users will start using karaf 4 with their legacy bundles we will get many more
people complaining about this.
So at least for Karaf 4.0.0 we should not enable checking for service
capabilities by default. Maybe we find a safe way to use this in one of the
next minor versions. For example I could imagine as flag in the feature
definition that enables checking for services.
