Change subject: restapi: Don't use inner classes in LinkBuilder ...................................................................... restapi: Don't use inner classes in LinkBuilder We use anonymous classes in a rather unusual way in the LinkBuilder. We do the follwing: whatever.setBody(new Body(){{setType(type);}}); Instead of this: Body body = new Body(); body.setType(type); whatever.setBody(body); The former is probably nicer syntax, but it has the side effect of introducing a synthetic field in the anonymous subclass of Body that the compiler generates automatically. This synthetic field is a reference to the outer LinkHelper class. When Jackson tries to convert this object to JSON it finds the synthetic field, and tries to serialize it as well. This fails because the LinkHelper class doesn't have a suitable constructor. The net effect is an error when the server tries to return an error message to the user. The solution is to avoid completely the anonymous classes, and thus the synthetic fields.
