Comment 2 Jesse Glick 2011-01-22 00:05:19 UTC 
Not clear there is anything to be done about it; I am presuming it is unreproducible. Might or might not be solved by a Lucene upgrade.
Comment 3 Tomas Danek 2011-01-24 07:47:52 UTC 
In fact, this one comes from  preintegration testing of new version of lucerne and mvn indexer. Tomas Z. was interested to take a look at this stracktrace. 
Anyway RANDOM kw is correct.
Comment 4 Tomas Zezula 2011-01-24 18:47:24 UTC 
Does not seem to be Lucene 3.x specific. The Directory implementations are "same" in 2.9 and 3.0.
Maybe related to Thread.interrupt() Doesn't maven do it? If so, index should use SimpleFSDirectory as described (by red color) in Javadoc here: http://lucene.apache.org/java/3_0_3/api/core/org/apache/lucene/store/NIOFSDirectory.html

The SimpleFSDirectory is slower if multiple threads are querying the same index, but this is not the case of NB.

I don't think so, but not sure.

> index should use SimpleFSDirectory

OK - do you want to make the change, or assign to me?
Comment 6 Tomas Zezula 2011-01-24 19:31:16 UTC 
I can do it.
But I would first try to reproduce it with Tomas Musil.
Comment 7 Tomas Danek 2011-01-27 10:40:00 UTC 
I was not able to reproduce in #20100127 even after a lot of attempts:(

Comment 8 Jesse Glick 2011-01-27 13:17:39 UTC 
OK. Probably random and unusual. The Maven indexer should probably react to IOException's like this more gracefully, perhaps by discarding the potentially corrupt index and starting over.
Comment 9 Jesse Glick 2011-12-20 19:02:16 UTC 
Only one report, probably not worth investigating.
