NPE and bundleContext.getBundle(0) with feature jar from 4.1.3-SNAPSHOT

[J. Brebec]

Hello,

I am using Karaf 4.1.2 with the bundle features from Karaf 4.1.3-SNAPSHOT.

Randomly, my integration tests fails on internals classes from Aries, Felix etc 
when this librairies tries to get the system bundle : getBundle(0) return null

I don't see when this bundle can be null, and I suspect that the region hook 
hides the system bundle.. If I use the jar from Karaf 4.1.2, then my 
integrations tests pass.

Is this a known issue with Karaf 4.1.3 ?
