Describe the bug

I have a simple data class being returned by one of my routes.

Data class:

data class Fruit(val id: Long, val name: String)

Route:

@Path("/fruit")
class FruitRoutes {

    @GET
    fun getAllFruit(): Multi<Fruit> {
        return Fruit.findAll()
    }
}

Expected behavior

The schema generated by the quarkus-smallrye-openapi extension has the id field as required:

components:
  schemas:
    Fruit:
      required:
      - name
      - id
      type: object
      properties:
        id:
          format: int64
          type: integer
        name:
          type: string

Actual behavior

The schema generated by the quarkus-smallrye-openapi extension does not have the id as required:

components:
  schemas:
    Fruit:
      required:
      - name
      type: object
      properties:
        id:
          format: int64
          type: integer
        name:
          type: string

Additional information

This can be fixed by adding @Schema(requiredProperties = ["id", "name", "createdAt"]) to the class, but it shouldn't be necessary.
