ERROR ResourceLeakDetector:171 - LEAK: ByteBuf.release() was not called before it's garbage-collected

When I do a load test for this simple service (relevant classes are there below)

@Path("/hello")
public class MyService {

    @POST
    @Path("/payloadCheck")
    @Consumes("application/json")
    @Produces("application/json")
    public Response get(MessageFormat msg) {
        return Response.status(Response.Status.OK).entity(msg).build();
    }
}

public class MessageFormat {
    private String size;
    private String payload;

    public String getSize() {
        return size;
    }

    public void setSize(String size) {
        this.size = size;
    }

    public String getPayload() {
        return payload;
    }

    public void setPayload(String payload) {
        this.payload = payload;
    }
}

public class Application {
    public static void main(String[] args) {
        new MicroservicesRunner()
                .deploy(new MyService())
                .start();
    }
}

The error on the terminal is
ERROR ResourceLeakDetector:171 - LEAK: ByteBuf.release() was not called before it's garbage-collected. See http://netty.io/wiki/reference-counted-objects.html for more information.
