Client model generated from type object with additionalProperties not correctly deserialized

[uvoigt]

Hi,

with

    LocStringDto:
      required:
      - values
      type: object
      properties:
        values:
          type: object
          additionalProperties:
            type: string

it generates a field and constructor

    @NotNull
    @JsonProperty(JSON_PROPERTY_VALUES)
    private Map<String, @NotNull String> values;

    public LocStringDto(Map<String, String> values) {
        this.values = values;
    }

which constructs a null value map from this string

{
  "en" : "Test 1",
  "de" : "Test 2"
}

Is there any option that I am not aware of to create code that would be able to read that data?

It works if I declare the original LocStringDto which leads to the generated OpenAPI this way

@Serdeable
public class LocStringDto extends HashMap<String, String> {
}

OpenAPI is then

        name:
          type: object
          additionalProperties: true

for a property of type LocStringDto which is then correctly written and read
