>    Affects Versions: 4.1.2

>            Assignee: Guillaume Nodet

> If a bundle is installed when the FeatureService is started, then it is p=
ossible that this bundle is not associated to the default region. as a cons=
equence, every services exported by this bundle are not visible from the os=
gi container, until karaf is restarted.
> A real usecase :
> - A new karaf distribution, with a blueprint file in a folder managed by =
fileinstall ;
> - When the distribution is started, as fileinstall is started before the =
feature bundle, and the folder are watched asynchronously, the blueprint fi=
le is installed before or in the same time the featureservice is started
> =3D> the services exported by the blueprint file are not visible
> This race condition is located in the FeatureService activator : the digr=
aph is loaded, and every bundle not known are added to the default region. =
then, it subscribes a bundle-listener : If a bundle X is installed between =
the digraph loading and the subscription of the bundle listener, then this =
bundle X is not attached to the default region.
> On my machine, this issue happens 70% of the time on a cold start.
