[jira] [Comment Edited] (LUCENE-6129) Assert that terms enums, docs
enums and doc values are not leaked across threads
[ https://issues.apache.org/jira/browse/LUCENE-6129?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14255994#comment-14255994 ]

Yeah, my wording wasn't too accurate. Each thread will have an associated unique instance of the Thread class and this instance is always returned for currentThread(). I actually took some time to look up where this is stated in the jls... and couldn't find any explicit reference. The only one I did find is this one, which I think is equivalent.

> Terms enums, docs enums and doc values should only be consumed in the thread that they have been acquired in. We could add checks to Asserting* to make sure they never leak?
