Ritesh Nigam commented on LUCENE-2280:
--------------------------------------
Are you sure you're using a stock version 2.3.2 of Lucene?
- Yes, I checked the manifest of the jar.
I ask because... the line numbers in SegmentMerger (specifically 566) don't
correlate to 2.3.2. The other line numbers do match. It's odd.
But looking at the code I don't see how either of the arrays being passed to
System.arraycopy can be null.
Can you turn on IndexWriter's infoStream and capture & post the output?
- I have turned on the infostream for IndexWriter, it will take some time to
get the result. once I get the result I will post that.
It's also strange that this leads to index corruption; it shouldn't (the merge
should just fail, and the index should be untouched). Can you run CheckIndex on
the index and post what corruption it uncovers.
- Here index corruption I mean that the main index file is getting deleted and
search is not returning expected result. Hence there is no index file exists
after the NullPointerExcepton, I cannot run CheckIndex.
Does this happen in a Sun JRE?
- I have not yet tested the same scenario on Sun JRE till now.

> I am using lucene 2.3.2 search APIs for my application, i am indexing 45GB

> but the only difference here is I am not using Store.Compress for my fields,

> Is this an issue with lucene?, if yes it is fixed in which version?
