environment

• canal version 5.7.25-log
• mysql version 1.1.6

Issue Description

Mysql 库很久没有数据变更，删除zk游标中的数据，canal.instance.master.timestamp设置了一个未来时间。

因为这里的
CanalEntry.Entry entry = parseAndProfilingIfNecessary(event, true);
解析出的都为NULL，导致logPosition.setPostion 没有赋值。
针对这种情况，将日志最新位点赋予logPosition比较合理
