https://issues.apache.org/jira/browse/HTTPCORE-370
官网原来的svn没了.
但是通过搜索github,搜索jira上的类AbstractMultiworkerIOReactor,找到了RELEASE_NOTES.txt:
https://github.com/apache/httpcomponents-core/blob/3b782acccfd20a290d0b3cd3206a5d44b5a9ec16/RELEASE_NOTES.txt
看到了上面jira上对应的修复
Release 4.3.2
* [HTTPCORE-370] Race condition if connection request succeeds and times out at the same time.
