DEFAULT_API_TIMEOUT_MS_CONFIG not working as expected


In my java application for kafkaProducer i created Admin and used this to list topics.
Admin admin1 = Admin.create(properties).
ListTopicsResult listTopicResult = admin1.listTopics();
When producer was not able to connect to broker thread get stucks at listTopic step.

To avoid this i have added DEFAULT_API_TIMEOUT_MS_CONFIG property and have set to 2000ms. so after 2s is producer is not able to connect to broker timeout should happen.
But this does not work as expected.

Is there any other way to achieve timeout or do we need to configure it in any other way?
Also is using AdminClient instead of Admin can have any impact.

Thanks in advance
