> I am looking at a strange situation starting Sling Trunk build. Not all
> namespace prefixes seem to be registered in the Loader class of the JCR Base
> bundle.
> IMHO the setup in the JCR Base Bundle between the AbstractSlingRepository and
> the Loader is not optimal:
> * AbstractSlingRepository implements SynchronousBundleListener
> to just forward the events to the Loader
> * There is a time gap between the time the Loader class is
> instantiated (and handling a set of bundles) and the time
> AbstractSlingRepository is registered as a bundle listener
> * There is a bug in the Loader constructor preventing all
> just INSTALLED bundles from being registered by the BundleListener
> only handles the INSTALLED (and UNINSTALLED and UPDATED) events.
> The last part will certainly miss some bundles.
> I suggest we change this setup such, that the Loader itself is the bundle
> listener handles the events itself. The AbstractSlingRepository just sets up
> the loader and uses it.
> As a result handling events is completely where it should be (in the Loader)
> and the AbstractSlingRepository does not leak implementation detail (being a
> bundle listener) to downstream extensions of the class.
