> Hi 
> I see there's a missalingment between the features dependencies and the pom of the camel-kafka component that makes impossible to run a Producer in karaf. I can see that in the features.xml 
> {code:xml}
> <bundle dependency='true'>mvn:org.apache.servicemix.bundles/org.apache.servicemix.bundles.kafka-clients/${kafka-clients-bundle-version}</bundle>
>     <bundle dependency='true'>mvn:org.apache.servicemix.bundles/org.apache.servicemix.bundles.kafka_2.10/${kafka-bundle-version}</bundle>
> {code}
> It's trying to use 2.10 scala version, but in the pom.xml we point to 2.11 scala version
> {code:xml}
>  <dependency>
>       <groupId>org.apache.kafka</groupId>
>       <artifactId>kafka_2.11</artifactId>

> I see this is already fix in master... so this should not apply to 2.17.0
