@kumarpritam863 - you are correct, my mistake, I have posted wrong exception
- this one is correct and it has been raised after modification of close()
method to the listing:
```
@Override
public void close(Collection<TopicPartition> closedPartitions) {
stopCoordinator();
stopWorker();
KafkaUtils.seekToLastCommittedOffsets(context);
}
```
Exception pointing to line: KafkaUtils.seekToLastCommittedOffsets(context);
```
java.lang.NullPointerException: Cannot invoke "Object.getClass()" because
"context" is null

```
Then we have realized that IcebergSinkTask.close() handles also partition: 0
reassignment and we have reverted code back.
Our next tests were focused on IcebergSinkTask.stop().
