@HuangXingBo @dianfu I am removing the Java class Time in this refactoring but struggle with the flink-python code. CI fails repeatedly with the following error:

Sep 05 18:51:05 >           raise Py4JError("{0} does not exist in the JVM".format(new_fqn))
Sep 05 18:51:05 E           py4j.protocol.Py4JError: org.apache.flink.streaming.connectors.kafka.FlinkKafkaProducer does not exist in the JVM

The error doesn't occur without my changes, so I assume that it's caused by the PR. But the error message seems unrelated (I didn't touch FlinkKafkaProducer). And I don't find any hint where to look for the cause of the issue.

Could you help a bit here or point me to someone who could?

Ok, looks like the Time class cannot be deleted because other libraries (e.g. flink-connector-kafka with [FlinkKafkaProducer:29](https://github.com/apache/flink-connector-kafka/blob/main/flink-connector-kafka/src/main/java/org/apache/flink/streaming/connectors/kafka/FlinkKafkaProducer.java#L29] still rely on it)

I overlooked the hint in the e2e test failure.

I reverted the removal of the Time class and labeled it as @Internal. Let's see whether that fixes the issue. :crossed_fingers:

Thanks for picking this one up, @zentol . I addressed you one change request and will squash-merge the PR after another CI run.

The current CI failure is related to FLINK-36279.

force-pushed a rebase to master after FLINK-36279 was merged.
