Bug Report Checklist

  • Have you provided a full/minimal spec to reproduce the issue?
  • Have you validated the input using an OpenAPI validator (example)?
  • What's the version of OpenAPI Generator used?

  • What's the actual output vs expected output?
  • [Optional] Bounty to sponsor the fix (example)
Description

When defining a schema that looks like this:

components:
SomeObject:
type: object
properties:
empty_map:
type: object
additionalProperties: false

We would expect to only accept this payload:
{"empty_map": {}}
But our code ends up accepting javascript objects with any values and any number of key value pairs.

@sebastien-rosset

openapi-generator version

Master branch

OpenAPI declaration file content or url

See the above example

Command line used for generation

any generator
this came up in python-experimental in #6290

Steps to reproduce

Generate a model for the above schema and check the validations in that model

Related issues/PRs
Suggest a fix

When this condition is seen (property schema of type object with no properties and additionalProperties: False) in Java we need to set the maxItems for this property to 0.
