JPA Derived Identifier doesn't work anymore with JDL

[murdos]

Overview of the issue

OneToOne relationship with jpaDerivedIdentifier is generated as a standard (non jpaDerivedIdentifier) OneToOne relationship.

Reproduce the error

With the following JDL:

application {
    config {
        baseName mapsIdBug
        applicationType microservice
        databaseType sql
        prodDatabaseType postgresql 
    }
    entities *
}

entity A

entity B

relationship OneToOne {
  A to B with jpaDerivedIdentifier
}

Both A.java and B.java contains a generated Id:

    @Id
    @GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "sequenceGenerator")
    @SequenceGenerator(name = "sequenceGenerator")
    private Long id;

The issue comes from the generated entity json file:

{
    "name": "A",
    "fields": [],
    "relationships": [
        {
            "relationshipType": "one-to-one",
            "otherEntityName": "b",
            "otherEntityRelationshipName": "a",
            "relationshipName": "b",
            "otherEntityField": "id",
            "ownerSide": true,
            "options": {
                "useJPADerivedIdentifier": true
            }
        }
    ],
    "changelogDate": "20191106101718",
    "entityTableName": "a",
    "dto": "no",
    "pagination": "no",
    "service": "no",
    "jpaMetamodelFiltering": false,
    "fluentMethods": true,
    "readOnly": false,
    "clientRootFolder": "",
    "applications": [
        "mapsIdBug"
    ]
}

In previous versions (before jhipster/jhipster-core#349 I think), JSON would have been:

{
    "name": "A",
    "fields": [],
    "relationships": [
        {
            "relationshipType": "one-to-one",
            "otherEntityName": "b",
            "otherEntityRelationshipName": "a",
            "relationshipName": "b",
            "otherEntityField": "id",
            "ownerSide": true,
            "useJPADerivedIdentifier": true
        }
    ],
    "changelogDate": "20191106101718",
    "entityTableName": "a",
    "dto": "no",
    "pagination": "no",
    "service": "no",
    "jpaMetamodelFiltering": false,
    "fluentMethods": true,
    "readOnly": false,
    "clientRootFolder": "",
    "applications": [
        "mapsIdBug"
    ]
}
