Some database Null value are converted to 0

[e-marchand]

an integer field declared optional receive 0 value instead of null

    @JsonProperty("numScelleBouteille") val numScelleBouteille: Int? = null,

Generated code show that null is accepted

CREATE TABLE IF NOT EXISTS `Lots` (`photo1` TEXT, `photo2` TEXT, `photo3` TEXT, `dateOperationDTMC` TEXT, `installations` TEXT, `analyse` INTEGER, `volume` REAL, `dateOperation` TEXT, `heurePrelevement` TEXT, `modalitePrelevement` INTEGER, `numScelleBouteille` INTEGER, `signataire` TEXT, `signature` TEXT, `volumeDTMC` REAL, `numLot` TEXT, `lot_S_K` TEXT, `lot_QS` INTEGER, `operateur` TEXT, `produit` TEXT, `millesime` TEXT, `typeOperation` TEXT, `installationOperation` TEXT, `installationStockage` INTEGER, `origineLot` TEXT, `analyseTransmise` INTEGER, `commentaire` TEXT, `__KEY` TEXT NOT NULL, `__STAMP` INTEGER, `__GlobalStamp` INTEGER, `__TIMESTAMP` TEXT, PRIMARY KEY(`__KEY`))");

 _columnsLots.put("numScelleBouteille", new TableInfo.Column("numScelleBouteille", "INTEGER", false, 0, null, TableInfo.CREATED_FROM_ENTITY));
