---------------------------------------

             Summary: addRepository() in cellar feature mbean always throws null pointer exception
                 Key: KARAF-4601
                 URL: https://issues.apache.org/jira/browse/KARAF-4601
             Project: Karaf
          Issue Type: Bug
          Components: cellar-core
    Affects Versions: 4.0.6
         Environment: WIndows 7, Java 8
            Reporter: Rakesh R. Prasad
            Priority: Blocker


When you invoke any addRepository() methods via JMX, CellarFeatureMBeanImpl.java throws a
null pointer exception always. 

Seems like the code is deliberately passing a null value to a map which doesn't accept null
values. 

{code:title=CellarFeaturesMBeanImpl.java:447}
CellarFeaturesMBeanImpl.java:447
if (name == null) {
     Features repository = JaxbUtil.unmarshal(uri.toASCIIString(), true);
     clusterRepositories.put(uri.toString(), name);
//....
{code}


The call stack is.
