In Flink we usually try to avoid Guava usages. Would it be easy to switch
to `Collections.unmodifiableList`?

> Key: FLINK-6996
> URL: https://issues.apache.org/jira/browse/FLINK-6996
> Project: Flink
> Issue Type: Bug
> Components: Kafka Connector
> Affects Versions: 1.2.0, 1.3.0, 1.2.1, 1.3.1
> Reporter: Piotr Nowojski
> Assignee: Piotr Nowojski
>
> FlinkKafkaProducer010 doesn't implement CheckpointedFunction interface. This
> means, when it's used like a "regular sink function" (option a from [the java
> doc|https://ci.apache.org/projects/flink/flink-docs-master/api/java/org/apache/flink/streaming/connectors/kafka/FlinkKafkaProducer010.html])
> it will not flush the data on "snapshotState" as it is supposed to.
