Данная ошибка возникает при вызове Rest метода:

@POST
@Path("getId")
@Produces(MediaType.APPLICATION_JSON)
@Consumes(MediaType.APPLICATION_JSON)
public Response getId(String data){
    JSONObject objectResponse = null;
    System.out.println("getId");
    try {
        ...
    }catch (JSONException ex) {
        Logger.getLogger(RequestWithMyIp.class.getName()).log(Level.SEVERE, null, ex);
    }
    if(objectResponse==null)
        return Response.status(404).entity("").build();
    else
        return Response.status(200).entity(objectResponse).build();
    }
}

 

при возврате ответа:

return Response.status(200).entity(objectResponse).build();

 

Исправляется данная ошибка, вызовом метода toString() у JSONObject объекта objectResponse :

return Response.status(200).entity(objectResponse.toString()).build();
