Inconsistent missing import of ParseNodeHelper

[andreaTP]

Description

With kiota 1.6.1 there are situations where, sometimes, the import of ParseNodeHelper is missing.

Reproducer

A minimal reproducer like this (coming from OpenAI OpenAPI spec):

openapi: 3.0.0
info:
  title: Test
  version: 1.0.0
  description: something
paths:
  /api/something/v1:
    post:
      requestBody:
        required: true
        content:
          application/json:
            schema:
              type: object
              properties:
                model:
                  description:
                  example: "text-embedding-ada-002"
                  anyOf:
                    - type: string
                    - type: string
                      enum: ["text-embedding-ada-002"]
                input:
                  description: |
                    Input text to embed, encoded as a string or array of tokens. To embed multiple inputs in a single request, pass an array of strings or array of token arrays. Each input must not exceed the max input tokens for the model (8191 tokens for `text-embedding-ada-002`) and cannot be an empty string. [Example Python code](https://github.com/openai/openai-cookbook/blob/main/examples/How_to_count_tokens_with_tiktoken.ipynb) for counting tokens.
                  example: "The quick brown fox jumped over the lazy dog"
                  oneOf:
                    - type: string
                      default: ""
                      example: "This is a test."
                    - type: array
                      items:
                        type: string
                        default: ""
                        example: "This is a test."
                    - type: array
                      minItems: 1
                      items:
                        type: integer
                      example: "[1212, 318, 257, 1332, 13]"
                    - type: array
                      minItems: 1
                      items:
                        type: array
                        minItems: 1
                        items:
                          type: integer
                      example: "[[1212, 318, 257, 1332, 13]]"
      responses:
        "200":
          description: "something"
          content:
            application/json: {}

emits (about 60-70% of the invocations, in Java) this snippet, in the file .../v1/V1PostRequestBody.java:

public static class V1 implements ComposedTypeWrapper, Parsable {
...
        public Map<String, java.util.function.Consumer<ParseNode>> getFieldDeserializers() {
            if (this.getV1Member1() != null) {
                return ParseNodeHelper.mergeDeserializersForIntersectionWrapper(this.getV1Member1());
            }
            return new HashMap<String, java.util.function.Consumer<ParseNode>>();
        }
...
}

without the corresponding using/import on the top of ParseNodeHelper.

Please, note that I'm unable to reproduce on top of the current main, but, I can notice that a bunch of getFieldDeserializers() generated methods are now returning empty maps, is it intended? Where can I look up the relevant changes?

Thanks a lot in advance! 🙏

The fixes I've applied in naming conventions for inline types most likely helped addressing this issue.
Can you expand on your last statement with the empty maps?

Nice, can you link the relevant PR 🙏

I haven't really gone through the code properly, and I'm having issues reproducing as the behavior is really inconsistent across runs (this is likely caused by the idempotency issue).

This is also going to have an impact once I have a fix.
#2769

Let me know once you can pinpoint a repro.

Thanks for all the answers!
