[nosql-dev] parasite properties (issue 259)

[Dmitry Repchevsky <redmitry@xxxxxxx>]

Hello,

As I already described in the 
https://github.com/eclipse/jnosql/issues/259 , there is a strange jnosql 
behavior while deseriaizing from mongodb with an empty (absent) object 
property.

CitizenRepository repository = service.getCitizenRepository();

----------------------------------------------------------------------------------- 

Citizen citizen = new Citizen();
citizen.setId("1234");
citizen.setName("Dmitry");

Citizen s = repository.save(citizen);

City city = s.getCity(); // ???
String name = city.getName(); // ???????
System.out.println("citizen.city.id = " + name);
-----------------------------------------------------------------------------------

There are two problems here.
1. Non existent "City" entity is created, while should be null
2. AbstractDocumentEntityConverter not only creates the "City" entity, 
but passes "Citizen" properties to initialize it, so we have the "City" 
with "id" and "name" taken from the "Citizen".

I attach my test project to see it.

Kind regards,

Dmitry
