> In order to face exception, several conditions must be met:
> 1) @EmbeddedMapping(nullIndicatorAttributeName = "city")
> annotation.
> 2) When persisting entity with embedded object, do not fill mentioned above
> "city" field.
> 3) Embedded object need to have another relation link (like in test project,
> Address -> Country).
