-----------------------------------------
Resolution: Fixed
> NullPointerException when adding a feature repository to a cluster
> ------------------------------------------------------------------
>
> Key: KARAF-4317
> URL: https://issues.apache.org/jira/browse/KARAF-4317
> Project: Karaf
> Issue Type: Bug
> Components: cellar-features
> Reporter: Roland Hauser
> Assignee: Jean-Baptiste Onofré
> Fix For: cellar-4.0.1
>
>
> I have a cluster with 2 nodes. Both nodes have the feature listener enabled
> (org.apache.karaf.cellar.node.cfg / feature.listener = true).
> On node 1, I install a custom feature repository with following command:
> {{feature:repo-add
> mvn:com.bechtle.terra/com.bechtle.terra.renderer.feature/LATEST/xml/features}}
> On node 2, I get a NullPointerException:
> {code}
> 2016-02-05 11:10:39,849 | ERROR | pool-50-thread-1 | RepositoryEventHandler
> | 64 - org.apache.karaf.cellar.features - 4.0.0 | CELLAR FEATURE:
> failed to add/remove repository URL
> mvn:com.bechtle.terra/com.bechtle.terra.renderer.feature/LATEST/xml/features
> java.lang.NullPointerException

> at java.lang.Thread.run(Unknown Source)[:1.7.0_55]
> {code}
> The same effect occurs when I use the dedicated cluster command:
> {{cluster:feature-repo-add default
> mvn:com.bechtle.terra/com.bechtle.terra.renderer.feature/LATEST/xml/features}}
> When I disable the feature listener (org.apache.karaf.cellar.node.cfg /
> feature.listener = false), the cluster-command
> {{cluster:feature-repo-add default
> mvn:com.bechtle.terra/com.bechtle.terra.renderer.feature/LATEST/xml/features}}
> works as exepected. The repository is then also available on node 2 and the
> feature can be installed.
> If I did something wrong, it would nevertheless be helpful if an error
> message would tell what caused the problem.
