[Question][Java] Operation parameter with oneOf schema, but generating server

I have rest specification with oneOf in parameters like https://github.com/OpenAPITools/openapi-generator/issues/19442

/users:
    get:
      operationId: getUsers
      summary: Get users by array of numbers OR array of strings
      description: "May pass string or integer array."
      parameters:
        - in: query
          name: identifiers
          description: "String or integer array"
          required: true
          style: form
          explode: true
          schema:
            oneOf:
              - type: string
              - type: integer
        - in: query
          name: someParam
          description: "Just parameter"
          required: false
          schema:
            type: string

It's all ok for client generator now.
But i'm trying to generate spring serverver and in model have only one model for this parameter:

@Generated(value = "org.openapitools.codegen.languages.SpringCodegen", comments = "Generator version: 7.10.0")
public interface GetUsersIdentifiersParameter {
}

May be i'm doing something wrong and need more parameters?

java -jar openapi-generator-cli-7.10.0.jar generate -i rest.yaml -g spring

If parameters are ok and it's boug or not realized feature - can it be realized (may be some suggestions for contribution) or it has no reason?

Start with the provided rest.yaml and run the documented openapi-generator-cli 7.10.0 Spring generation command, then inspect the generated GetUsersIdentifiersParameter interface. Compare the server output with the oneOf query-parameter schema and determine what generated representation would correctly preserve the string-or-integer parameter; done means server generation handles this parameter without producing only an empty model.
