Error with camel cxf-rs interceptor in fuse 6.2 with message- Payload: No message body writer has been found for class xxx.yyy.zz.Response

Issue

• I'm porting my software solution from fuse 6.1.1 to fuse 6.2.0 (I'm using version jboss-fuse-pre-patched-6.2.0.redhat-143-p1, patched with jboss-fuse-6.2.0.redhat-153-hf4) and I have some trouble with interceptor used in my camel rest service (the service is exposed with cxf rs-server).
• In the 6.1.1 version, I use the following blueprint configuration to use rest interceptor

<cxfi:bus>
    <cxfi:features>
        <cxfi:logging/>
    </cxfi:features>
    <cxfi:inInterceptors>
        <ref component-id="interceptor"/>
    </cxfi:inInterceptors>
</cxfi:bus>

• If I try to use the same code in the 6.2.2 version, I'm not more able to use the rest service; I have even problems to see the wadl xml descriptor from the cxf web console page.
