> Under normal circumstances osgi should not invoke any of the
> updatedPropertyProvider/unbindPropertyProvider methods after the
> resourceResolverFactory is deactivated - but it has been seen nevertheless.
> What can be done in OakDiscoveryService is to tolerate this and not issue a
> log.warn instead of throwing an uncaught IllegalArgumentException.
