> Cellar can stop bundles whereas it should not

>                 Key: KARAF-4664
>                 URL: https://issues.apache.org/jira/browse/KARAF-4664
>             Project: Karaf
>          Issue Type: Bug
>          Components: cellar-bundle, cellar-features
>    Affects Versions: cellar-4.0.1
>            Reporter: Jean-Baptiste Onofré

>             Fix For: cellar-4.0.2
> If we have a cluster of 2 nodes running, both with all the same bundles deployed and
activated. We stop the second node, then the first one. We start the first node, wait until
it is fully initialized, then start the second one. The issue is that sometimes second node
startup causes few bundles on the first node to stop.
> My guess is that the second node, when joining the cluster, pushes its state to the cluster
while some of its bundles are still starting and in RESOLVED state, which causes corresponding
bundles on the first node to stop and stay RESOLVED too. My hypothesis is supported by the
fact that once I change the "default.*.sync" options in the "org.apache.karaf.cellar.groups.cfg"
from "cluster" to "clusterOnly", the issue stops happening. However, I think we still should
support the "cluster" synchronization strategy if possible.
