[jira] [Commented] (SOLR-4300) Possible race condition in
CoreContainer.getCore() when lazily loading cores.
[ https://issues.apache.org/jira/browse/SOLR-4300?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13554325#comment-13554325 ]
Erick Erickson commented on SOLR-4300:
--------------------------------------
OK, I'm going to commit this this evening or tomorrow morning for both trunk, 4.1 & 4.x unless there are objections. I'll take another detailed pass over the code before I do on the theory that anything stupid will be clearer after not looking at it for a while.
My fears of deadlock are probably overblown. People don't _get_ to the code in question unless they're defining lazily-loaded cores, so "It shouldn't affect anyone not using the new functionality" (tm).

> Yonik pointed out in SOLR-1028 that there is a possible race condition here, he's right not to my surprise. Calling it a "blocker" for now so we make a decision on it rather than let it fall through the cracks. I should be able to get a patch up tonight (Sunday).
> That said, there's potential here to introduce deadlocks, is it worth rushing into 4.1?
