Cczzzz commented on issue #1800: Fix asynchronous send retry URL: https://github.com/apache/rocketmq/pull/1800#issuecomment-592387309 @xujianhai666 首先 incrementAndGet 和 getAndIncrement 一起使用肯定会出现，重复id的，比如我在测试的时候发现发送了两个请求id为11的请求。因为rocket是用map的记录的id为key就导致一个id为11的请求被覆盖了。之后会接受两个11的响应，这样第二的11的响应找不到对应的请求，也就执行不了对应的回调函数了。
