[BUG][Java] OpenApi3 to Angular model - generation with oneOf

While generating angular model based on openapi3 json specification, the entity of model generated for types marked as "oneOf" has wrong name including "oneOf" prefix. But this type is not available because it is generated in separated file with proper name without this prefix.

OpenApi Generator:
openapi-generator-cli-4.0.3.jar

Initial c# class:

public class ProfileDetail
{
    public ProfileData TypicalCustomerProfile { get; set; }
    public ProfileData OutlierCustomerProfile { get; set; }
}

Input OpenApi3 JSON definition:

  "ProfileDetail": {
    "type": "object",
    "additionalProperties": false,
    "properties": {
      "typicalCustomerProfile": {
        "nullable": true,
        "oneOf": [
          {
            "$ref": "#/components/schemas/ProfileData"
          }
        ]
      },
      "outlierCustomerProfile": {
        "nullable": true,
        "oneOf": [
          {
            "$ref": "#/components/schemas/ProfileData"
          }
        ]
      }
    }
  },

Generated model - incorrect:

import { OneOfProfileData } from './oneOfProfileData';

export interface ProfileDetail {
typicalCustomerProfile?: OneOfProfileData | null;
outlierCustomerProfile?: OneOfProfileData | null;
}

Expected:

import { ProfileData } from './ProfileData';

export interface ProfileDetail {
typicalCustomerProfile?: ProfileData | null;
outlierCustomerProfile?: ProfileData | null;
}

Reproduce the issue with openapi-generator-cli-4.0.3.jar using the supplied OpenAPI3 ProfileDetail schema and Angular generation. Inspect the Angular generator's handling of oneOf models, then verify that the generated ProfileDetail imports and references ProfileData rather than OneOfProfileData, with no oneOf-prefixed file reference.
