Fuse Server 6.2.0 ClassNotFoundException for RestletOperationException

Latest response

The following relates to running a Fuse 6.2.0.redhat-133 server from with Developer Studio 9.1.0 GA. I added the camel-restlet bundle using 'mvn:org.apache.camel/camel-restlet/2.15.1.redhat-620133'

I added an section to one of several routes in a Camel context in an OSGI bundle 'esb-services'. The route uses to invoke a REST endpoint defined using the restlet component. The esb-services bundle previously installed and started with no errors. The added section was:

        <onException redeliveryPolicyRef="BMSUpdateRedelivery">
            <exception>org.apache.camel.component.restlet.RestletOperationException</exception>
            <continued><constant>true</constant></continued>
            <setBody><simple>${exchangeProperty.failBody}</simple></setBody>
        </onException>

I'm able to unit test this route. However when I install the generated jar as a bundle in the same local Fuse server, I now get an exception:

Error occurred during starting Camel: CamelContext(esb-services) due Failed to create route ESBUpdateWhatsOnMediaAsset at: >>> OnException[null -> [SetBody[simple{${exchangeProperty.failBody}}]]] <<< in route: Route(ESBUpdateWhatsOnMediaAsset)[[From[{{whatson.mediaasset... because of org.apache.camel.component.restlet.RestletOperationException

The stack trace is:

org.apache.camel.FailedToCreateRouteException: Failed to create route ESBUpdateWhatsOnMediaAsset at: >>> OnException[null -> [SetBody[simple{${exchangeProperty.failBody}}]]] <<< in route: Route(ESBUpdateWhatsOnMediaAsset)[[From[{{whatson.mediaasset... because of org.apache.camel.component.restlet.RestletOperationException

So RestletOperationException is not picked up as being in the camel-restlet bundle, even though this shows the 'org.apache.camel.component.restlet' package as exported.

I also manually installed the camel-restlet feature but still get the same exception.

Now RestletOperationException extends CamelException which is in the org.apache.camel package in camel-core. If I change my route's to refer to org.apache.camel.CamelException instead of org.apache.camel.component.restlet.RestletOperationException, then when I install esb-services there are NO exceptions and all routes in esb-services start OK.

How can I use RestletOperationException as an exception I want to deal with in a Camel route?
