Remote getService() lookup with only component name fails when target has a callback

If I deploy a composite with the following component

<component name="SCAJFrontendComponent">
<implementation.java class="test.bindings.sca.FrontendImpl"/>

<service name="FrontendService">
<interface.java interface="test.bindings.sca.intf.FrontendService"/>
<binding.sca />
</service>

<reference name="backendService" target="SerializationBackendComponent">
<interface.java interface="test.bindings.sca.intf.SerializeBackendService"
callbackInterface="test.bindings.sca.intf.SerializeCallback"/>
<callback>
<binding.sca />
</callback>
</reference>
</component>

and try to do a getService lookup using just the component name on a different JVM, the lookup fails saying there are multiple services in the component and I need to specify a service name.
The check in DefaultEndpointFinder to check if the endpoint service is a callback service doesn't seem to be working in the remote case.
I think the code in the EndpointProcessor needs to be updated to include some attribute to indicate that the service is a callback service when it's getting serialized.
