Empty object as an array instead of object

[alibo]

for empty objects, it returns array instead of empty object ( { } ) :

Model:

Class Model {
    /**
     * @var int
     */
    public $status;

    /**
     * @SerializedName("data")
     * @PsonType("App\Api\Models\Responses\ResponseModel")
     * @var ResponseModel
     */
    public $data;
}

EmptyModel:

Class EmptyModel implements ResponseModel {

}

Serializing Model with Pson:

$model = new Model();
$model->status = 200;
$model->data = new EmptyModel();

echo $pson->toJson($data);

{ "status": 200, "data": [] }
