Apache camel rest dsl RestBindingMode.json is not working

I am trying to build rest api using camel-rest-dsl. I have tried with multiple provider, spark-rest, jetty. But it throwing marshelling exception when i use RestBindingMode.json, if i remove rest binding mode it works fine.

SpringRouteBuilder

@Component
public class RestAPIRoutes extends SpringRouteBuilder {

    @Override
    public void configure() throws Exception {
        restConfiguration().component("spark-rest")
            .bindingMode(RestBindingMode.json)
            .port(8787)
            .dataFormatProperty("prettyPrint","true");

        rest("/balance").produces("application/json").consumes("application/json")
            /* mock api */
            .get("/query").route().bean(BalanceService.class,"fetchBalance").endRest()
            /* fetch balance by msisdn*/
            .get("/query/{msisdn}").description("Fetch line balance by msisdn")
                .type(BalanceInfo.class).to("bean:balanceService?method=fetchBalance(${header.msisdn})")
            .post("/update").type(BalanceInfo.class).outType(BalanceInfo.class).to("bean:balanceService?method=updateBalance");

    }

}

Here balanceService is a simple Spring @Service with overloaded method and BalanceInfo is simple pojo class with two field and getter setters.
