Operations on SwitchYard REST binding interface does not allow more than one parameter

Issue

• User faces an issue while trying to define a REST binding interface with operations having more than one Query/Path parameters as follows. It has been observed that in such scenarios SwitchYard REST binding is not allowing more than one parameter.

@GET
@Consumes({ "application/json" })
@Produces("application/json")
public SimpleRestInterface search(@QueryParam("firstname") String firstname, @QueryParam("secondName") String secondName);

• Even users have written a custom MessageComposer class to wrap the multiple parameters into a single object as suggested in the following discussion https://developer.jboss.org/thread/230427 . However, when user tried to deploy the SwitchYard application it is throwing the below exception:
