Steps to Reproduce:
Hide

Slightly modify the quickstart here, jboss-fuse-6.2.1.redhat-084/quickstarts/cxf/rest to have blueprint file as mentioned in the description.

Attached is the reproducer, rest.zip.

When you hit the request with the url, 'http://localhost:9000/swaggerFeature/api-docs', you can see 'Error: 500' and the NPE in the fuse logs

The reproducer works fine in Fuse 6.1. We don't see any issue there.

Workaround is to use the 'swagger-maven-plugin'.

When accessing swagger /api-docs with jax-rs server configured with a non-default HTTP port (e.g http://localhost:9000/api), Swagger API throws NullPointerException.

If the configuration of jaxrs server is like below,

<jaxrs:server id="customerService" address="http://localhost:9000/swaggerFeature">
        <jaxrs:serviceBeans>
            <ref component-id="customerSvc"/>
        </jaxrs:serviceBeans>
        <jaxrs:providers>
           <bean class="com.fasterxml.jackson.jaxrs.json.JacksonJsonProvider"/>
        </jaxrs:providers>
        <!--<jaxrs:features>
            <bean class="io.fabric8.cxf.endpoint.SwaggerFeature">
                <property name="title" value="Fabric8:CXF:Quickstarts - Customer Service" />
                <property name="description" value="Sample REST-based Customer Service" />
                <property name="version" value="6.2.1.redhat-084" />
            </bean>
        </jaxrs:features>-->
	<jaxrs:features>
		<bean class="org.apache.cxf.jaxrs.swagger.SwaggerFeature" />
	</jaxrs:features>
    </jaxrs:server>
 
    <cxf:bus>
        <cxf:features>
          <cxf:logging />
        </cxf:features>
    </cxf:bus> 
    <bean id="customerSvc" class="io.fabric8.quickstarts.rest.CustomerService"/>

you get the below NPE logging in the Fuse logs,
