InputStream - cannot find symbol

[oliverblaha]

Expected Behavior

The correct import for InputStream (java.io.InputStream) should be generated when building a client.

Actual Behaviour

An import for InputStream below the generated model is added, which causes compilation to fail.
I followed the OpenAP client guide, but replaced the OpenAPI definition by another one (which is provided to me by a third party, therefore I'd prefer not to have to have to modify it for maintainability reasons). Example below.

Note: I'm only building a client, I don't know if this affects server building, too.

Steps To Reproduce

1. Follow : https://guides.micronaut.io/latest/micronaut-openapi-generator-client-gradle-java.html
2. Replace the OpenAPI definition with this one:

---
openapi: "3.0.3"
info:
  version: "v1"
  title: "Dummy"
paths:
  /assets:export:
    get:
      operationId: "Dummy"
      description: ""
      parameters:
        - name: "query"
          in: "query"
          description: ""
          required: false
          schema:
            type: "string"
      responses:
        "200":
          description: ""
          content:
            '*/*':
              schema:
                type: "string"
                format: "binary"

3. Build it.
4. Observe that the generated DefaultApi contains an invalid import of InputStream (import example.openmeteo.model.InputStream):

/*
 * Dummy
 * No description provided (generated by Openapi Generator https://github.com/openapitools/openapi-generator)
 *
 * The version of the OpenAPI document: v1
 * 
 *
 * NOTE: This class is auto generated by OpenAPI Generator (https://openapi-generator.tech).

package example.openmeteo.api;

    /**

     * @param query  (optional)
     *
     * @return InputStream
     */
    @Get("/assets:export")
    InputStream dummy(
        @QueryValue(value = "query") @Nullable String query
    );
}
