feature.xml file for Camel has unresolved placeholder in camel-cxf feature

Willem can you take a look at this. Its important that the Camel 2.8 branch works fine. The camel-cxf feature is broken.

eg as you can see in the bundle entry, then ${jaxws.api.version} is not resolved.
<bundle dependency="true">mvn:org.apache.servicemix.specs/org.apache.servicemix.specs.jaxws-api-${jaxws.api.version}/1.8.0</bundle>

There is 3 different API versions in the maven repo
http://repo2.maven.org/maven2/org/apache/servicemix/specs/

At Apache, we are now using the feature of Apache CXF directly, so the camel-cxf is much smaller
<repository>mvn:org.apache.cxf.karaf/apache-cxf/2.4.2/xml/features</repository>
