Issue with controller validators generated with OpenApi Generator

So I have used OpenApi Generator to generate java classes (controller interfaces and response class). But because I set flag user-optional to true, every parameter which is not required in request is wrapped as Optional, but if I add constrains to min and max value my parameters looks like following: @Min(1) @Max(10) Optional<Long> value, and obviously my java app is not happy because there is no such validator which will validate Optional.

My snippet of generator file looks like that:

/test:
  get:
    tags:
      - test
    summary: Make it work already
    parameters:
      - name: id
        in: query
        required: true
        schema:
          type: string
      - name: range
        in: query
        required: false
        schema:
          type: integer
          format: int64
          minimum: 1
          maximum: 10
          .
          .
          . etc

And second parameter looks like that @Min(1) @Max(10) @RequestParam(value="range", required = false) Optional<Long> value

Is there way to tell OpenApi to put validators inside of Optional?
