I think it is in clear() because removing `flush()` produces the following output:\r\n\r\n```\r\n[1, 2]\r\n[1, 2]\r\n[1, 2]\r\n```\r\n\r\nIt seems that `clear()` has no effect at all in this case.","author":{"url":"https://github.com/isopov","@type":"Person","name":"isopov"},"datePublished":"2018-02-12T11:51:30.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":1},"url":"https://github.com/458/msgpack-java/issues/458"}
