Subject Re: Lucene Indexing error
Date Fri, 28 Sep 2007 13:40:59 GMT
Hi,

> So is there any fix for this in Jackrabbit/Lucene?

No, I don't think there is. Could you please log a bug in the Jackrabbit JIRA
at http://issues.apache.org/jira/browse/JCR ?
It would be great if you have a reproducible test case, but if not
please provide some more information about your environment
(Java version, OS, file system used) and the operations you execute.
Also, do you use multiple session, concurrently access the same session using
multiple threads, use multiple workspaces, versioning?

Thanks,
Thomas
