Earwin Burrfoot commented on LUCENE-2386: ----------------------------------------- I'm at loss for words. No, seriously, basing your logic on the content of user-targeted error message? Btw, opening DirectoryReader on an empty directory fails with exception too. That's why some people might do this before opening - "new IW().close()", like I did. While trivial to fix, this has to be fixed, or an app breaks when started with an empty index directory. > IndexWriter commits unnecessarily on fresh Directory > ---------------------------------------------------- > > Key: LUCENE-2386 > URL: https://issues.apache.org/jira/browse/LUCENE-2386 > Project: Lucene - Java > Issue Type: Bug > Components: Index > Reporter: Shai Erera > Assignee: Shai Erera > Fix For: 3.1 > > Attachments: LUCENE-2386.patch > > > I've noticed IndexWriter's ctor commits a first commit (empty one) if a fresh > Directory is passed, w/ OpenMode.CREATE or CREATE_OR_APPEND.
