OpenAPI 1.6.11 Swagger UI showing PetStore by default if SerializationFeature.WRAP_ROOT_VALUE is enabled in jackson-databind ObjectMapper

Question

I am using OpenAPI 1.6.11 (1.6.12 the latest one works also) with Spring Boot 2.3.3.RELEASE.

I have defined ObjectMapper like below:

@Configuration
public class CombinedApiConfiguration {

@Bean
@Primary
public ObjectMapper objectMapper() {
    ObjectMapper mapper = new ObjectMapper();
    JaxbAnnotationModule module = new JaxbAnnotationModule();
    mapper.registerModule(module);
    mapper.registerModule(new JavaTimeModule());
    mapper.enable(SerializationFeature.INDENT_OUTPUT);
    mapper.setSerializationInclusion(JsonInclude.Include.NON_NULL);
    mapper.setSerializationInclusion(JsonInclude.Include.NON_EMPTY);
    mapper.enable(SerializationFeature.WRAP_ROOT_VALUE);
    mapper.enable(DeserializationFeature.UNWRAP_ROOT_VALUE);
    mapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false);
    mapper.configure(JsonGenerator.Feature.WRITE_BIGDECIMAL_AS_PLAIN, true);
    mapper.configure(MapperFeature.ACCEPT_CASE_INSENSITIVE_PROPERTIES, true);
    mapper.registerModule(new XMLCalendarModule());
    DateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSSXXX");
    mapper.setDateFormat(dateFormat);
    mapper.configure(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS, false);
    mapper.disable(DeserializationFeature.ADJUST_DATES_TO_CONTEXT_TIME_ZONE);
    mapper.getSerializerProvider().setNullValueSerializer(new JsonSerializer<Object>() {
        @Override
        public void serialize(Object o, JsonGenerator jsonGenerator, SerializerProvider serializerProvider) throws IOException {
                jsonGenerator.writeString("");
            }
        });
        return mapper;
    }
}

so when I hit swagger url ( http://localhost:8099/swagger-ui/index.html) it shows PetStore as below:

Now it will work (it will show my APIs instead of PetStore) only if I comment a line in object mapper class:

// mapper.enable(SerializationFeature.WRAP_ROOT_VALUE);

and the output will be like below as expected:

All I do not want to do is comment that line in Object Mapper. Could anyone please help me with this ?

Thank you very much.
