Review Comment:
This is some leftover...I just wanted to cover two scenarios:
1. > sign, which throws expectation
```java
configs.put(ProducerConfig.DELIVERY_TIMEOUT_MS_CONFIG, 1000);
configs.put(ProducerConfig.LINGER_MS_CONFIG, 1000);
configs.put(ProducerConfig.REQUEST_TIMEOUT_MS_CONFIG, 1);
```
2. and equality sign
```java
configs.put(ProducerConfig.DELIVERY_TIMEOUT_MS_CONFIG, 1000);
configs.put(ProducerConfig.LINGER_MS_CONFIG, 999);
configs.put(ProducerConfig.REQUEST_TIMEOUT_MS_CONFIG, 1);
```
I have modified the code, now it should be correct.
