Subject Re: [jira] [Commented] (LUCENE-8809) Refresh and rollback concurrently can leave segment states unclosed
Date Thu, 23 May 2019 15:59:40 GMT
Hi Nhat,

Commits to branch_8_1 are not allowed now due to the fact that this branch is used for the
8.1.1 release - any critical bug fixes should be first submitted to JIRA as a patch and approved
by the release coordinator (in this case me). Please revert your latest commit from branch_8_1.
