@yuriyz @jmunozherbas Why we need this method on ORM layer. It not works with DB. The better place for it is in reusable service layer.

@jmunozherbas in PR description you added reference to #260
But it's about another update. Is there design of this update?

@qbert2k Can you share design related to LocalizedString?

Why we simply can't use?

    @JsonObject
    @AttributeName(name = "attrbute_name")
    private LocalizedString attributeValueWhichOrmWill convertToJson;

[yuriyz]

Right, this particular PR comes out of what was done in LDAP entry manager for LocalizedString. We are forced to update other entry managers with what we have now. So we have to decide how do we proceed with persistence of LocalizedString. Simple json looks quite feasible. Lets see what @qbert2k say.
