Luca Tagliani commented on JCR-3299:
------------------------------------
With this code the indexes are rebuilt even if they are consistent.
I have this problem and using Luke 3.5.0 (http://code.google.com/p/luke/) I can
open the indexes and it seems they are consistent.
So I was wondering if it's possible to rebuild only the indexes_xxxx file after
checking the indexes consistence with Lucene?

> Project: Jackrabbit Content Repository
> Issue Type: Bug

> Writing a new IndexInfos to disk is not atomic. It may happen that e.g. an
> empty indexes_xxxx file is placed into the index directory when the JVM is
> killed. A subsequent startup will then fail with a exception like this:
> Caused by: java.io.EOFException

> The lucene directory abstraction does not expose a method anymore to
> atomically rename a file, which would probably be the preferred way to fix
> this. Instead I suggest we make the initialization more resilient and catch
> these kind of cases.
