Issue

Below steps you should take to reproduce the problem.

1. Get clean Fuse 6 container (data folder removed)
2. Build and install two attached artifacts
3. Open karaf console and execute in the following order (order does matter)

features:addurl mvn:com.example.esb/camel-cxf-test/1-SNAPSHOT/xml/features
features:install camel-cxf-test

features:addurl mvn:com.example.esb/camel-rest-test/1-SNAPSHOT/xml/features
features:install camel-rest-test

features:uninstall camel-cxf-test
features:uninstall camel-rest-test

features:install camel-cxf-test
features:install camel-rest-test

After last command I see following exception:

But if we change the order of deployment everything works. Below steps when everything works:

1. Get clean Fuse 6 container (data folder removed)
2. Build and install two attached artifacts
3. Open karaf console and execute in the following order (order does matter)
   features:addurl mvn:com.example.esb/camel-rest-test/1-SNAPSHOT/xml/features
   features:install camel-rest-test

features:addurl mvn:com.example.esb/camel-cxf-test/1-SNAPSHOT/xml/features
features:install camel-cxf-test

features:uninstall camel-rest-test
features:uninstall camel-cxf-test

features:install camel-rest-test
features:install camel-cxf-test
