@Test(timeout = 30000L)

			resumeProducer.commitTransaction();
		} finally {
			resumeProducer.close(Duration.ofSeconds(5));
		}

		assertRecord(topicName, "42", "42");

		// this shouldn't throw - in case of network split, old producer might attempt to commit it's transaction
		kafkaProducer.commitTransaction();

		// this shouldn't fail also, for same reason as above
		resumeProducer = new FlinkKafkaInternalProducer<>(extraProperties);
		try {
			resumeProducer.resumeTransaction(producerId, epoch);

			resumeProducer.close(Duration.ofSeconds(5));
