Why creating offline repository fails with Unable to find the feature 'pax-jetty' error in Fuse 6.1.0 ?

Issue

• While building custom offline repository for JBoss Fuse 6.1 we are receiving "pax-jetty" and "pax-http" related errors like following

  [ERROR] Failed to execute goal org.apache.karaf.tooling:features-maven-plugin:2.2.1:add-features-to-repo (add-features-to-repo) on project offline-repo: Error populating repository: Unable to find the feature 'pax-jetty' -> [Help 1]
  [ERROR] Failed to execute goal org.apache.karaf.tooling:features-maven-plugin:2.2.1:add-features-to-repo (add-features-to-repo) on project offline-repo: Error populating repository: Unable to find the feature 'pax-http' -> [Help 1]
  

• We went through all the steps in the documentation located here: https://access.redhat.com/documentation/en-US/Red_Hat_JBoss_Fuse/6.1/html/Deploying_into_the_Container/Locate-CustomRepo.html Still it is causing the above error.

• Depending on which feature is removed a "Unable to find the feature 'pax-http'" error also occurs along with "Unable to find the feature 'pax-jetty'".
• Is it related to https://issues.apache.org/jira/browse/KARAF-2212. The error comes up because of a missing repository or descriptor in the "pom.xml".
• Is it correct that the custom offline repo would work this would be enough to let Fuse work in an offline eviroment?
• The offline maven repository with all project dependencies like camel / third partie stuff etc. would be just for developement building purpose, right?
• Does Fuse itself also need to download maven dependencies at runtime?
