Test project attached.
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).
