JavaSpring codegen ignores per-field required setting

Given the below OAS 3 spec

paths:
  /survey:
    post:
      requestBody:
        required: true
        content:
          application/x-www-form-urlencoded:
            schema:
              type: object
              properties:
                name:
                  type: string
                age: 
                  type: integer
              required:
                - name

The expectation is to require a non-null request body but only name to be mandatory. The age property should become optional. However, when code is generated it produces:

    @RequestMapping(value = "/survey",
        consumes = { "application/x-www-form-urlencoded" },
        method = RequestMethod.POST)
    default ResponseEntity<Void> operation(
        @Parameter(in = ParameterIn.DEFAULT, description = "",schema=@Schema()) @RequestParam(value="name", required=true)  String name, 
        @Parameter(in = ParameterIn.DEFAULT, description = "",schema=@Schema()) @RequestParam(value="age", required=true)  Integer age) {

Observe that age parameter in the generated method signature has required=true when it's clearly not required in the spec.

Start by reproducing the supplied OAS 3 application/x-www-form-urlencoded case in the JavaSpring generator and compare the generated method signature with the schema's required list. Done means the generated signature marks name as required, age as optional, and keeps the request body required.
