SwaggerParser didn't return a validator messages when specification has schema with `additionalProperties` type `object` with reference

Hi
Currently, I'm using the swagger parser for getting parsing OpenAPI objects from my given specification.

SwaggerParseResult parseResult = new OpenAPIV3Parser().readContents(openAPIFileContent, null, parseOptions);
        if (!parseResult.getMessages().isEmpty()) {
...
}

The used parser didn't return the validator for the schema which has additionalProperties type object and has a reference. but when it
Coding via the IDE returns as invalid usage of additionaltProperties.

IDE error

example for

components:
  schemas:
    User:
      type: object
      properties:
        name:
          type: string
        id:
          type: integer
    User01:
      description: Additional properties with objects with reference fields
      type: object
      properties:
        name:
          type: string
        id:
          type: integer
      additionalProperties:
        type: object
        $ref: "#/components/schemas/User"
   

Could you please let me know if is this regarding the version issue? I'm using the latest version 2.1.9

Start with the OpenAPIV3Parser.readContents entry point and reproduce the supplied OpenAPI example containing additionalProperties with type object and a $ref. Inspect how parseResult.getMessages() is populated during validation. Done means the parser reports the invalid additionalProperties usage instead of returning no validator messages.
