Description

I am attempting to set a custom HTTP binding on the Jetty component used with the REST DSL:

<bean id="jettyNoStackTraceHTTPBinding" class="ch.vivates.vel.rest.JettyNoStacktraceHttpBinding" />

<camelContext id="vel-jetty-rest-service" allowUseOriginalMessage="false" xmlns="http://camel.apache.org/schema/blueprint" streamCache="false">
    <restConfiguration component="jetty" scheme="http" host="{{vel.rest.host}}" port="{{vel.rest.port}}" contextPath="{{vel.rest.contextpath}}" bindingMode="json">
        <endpointProperty key="httpBindingRef" value="jettyNoStackTraceHTTPBinding" />
    </restConfiguration>

    <!-- ... -->

</camelContext>

The http binding is not picked up though. At runtime the custom binding does not get triggered.
The logs show the generated endpoint URL without the httpBindingRef query parameter:

2016-02-12 16:22:15,454 | INFO  | pool-37-thread-1 | BlueprintCamelContext            | 64 - org.apache.camel.camel-core - 2.16.2 |   | Route: route1 started and consuming from: Endpoint[jetty:http://0.0.0.0:8181/vivates/vel/event/%7Bid%7D?httpMethodRestrict=PUT]

However, if I try to specify a binding bean that does not exist I receive an error during context ramp-up (as would be expected); the endpoint URI logged in the error message includes the httpBindingRef query parameter:
