I am still running into a bit of trouble with Cellar 3.0.0-SNAPSHOT and am
not sure if I should back off to 2.3.0 for now (since I'm starting pretty
fresh with Karaf, I figure I might as well start with 3.0.0). Karaf 3.0.0
has been working great so far, but I feel like I have to be doing something
wrong with Cellar. I had gotten the integration tests partially running by
upgrading to pax-exam 2.6. I then worked through one or two other issues.
I'm now getting NPEs from the child instances in the integration tests
when I try to install cellar on them. I decided I should probably try
installing Cellar on a plain running Karaf 3.0.0 instance, here's what
happened when I added the repo and installed the cellar feature:

Is there a current known stability issue in Cellar 3.0.0 currently? Can I
use Karaf 3.0.0 and Cellar 2.2.5? Obviously there is always a risk of
issues with in-development software, I was just hoping to get a head start.
:)
Let me know if I should open an issue for anything, or if I can get anymore
information. When I debugged the NPE I was receiving in the Karaf child
instance in the integration tests, the NPE was caused by a null feature url
(even though the cellar feature url was being passed in).
