[jira] [Updated] (LUCENE-3829) Lucene40 codec's DocValues
DirectSource impls aren't thread-safe
[ https://issues.apache.org/jira/browse/LUCENE-3829?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Michael McCandless updated LUCENE-3829:
---------------------------------------
Attachment: LUCENE-3829.patch
Patch showing the failure (you have to remove the true || in
TestDocValuesIndexing.testWithThreads), and also (separately) adding
DV coverage to LineFileDocs for better test coverage.
I'll commit the patch shortly (it's tests only, and passing because I
disabled testing DirectSource with threads until we can fix this
issue; we still test Source with threads).

> I think...?
