Steven Rowe updated LUCENE-3188:
--------------------------------
Attachment: LUCENE-3188.patch
Patch against branch_3x.
I converted Ivan's test class into a unit test. Without Ivan's patch, the test
fails, and with the patch, it succeeds.
Here's the test failure I got without Ivan's patch:

> Key: LUCENE-3188
> URL: https://issues.apache.org/jira/browse/LUCENE-3188
> Project: Lucene - Java
> Issue Type: Bug
> Components: modules/other
> Affects Versions: 3.0, 3.2
> Environment: Bug is present for all environments.
> I used in this case - Windows Server 2003, Java Hot Spot Virtual Machine.
> Reporter: Ivan Dimitrov Vasilev
> Priority: Minor
> Fix For: 3.0, 3.2
>
> Attachments: IndexSplitter.java, LUCENE-3188.patch,
> LUCENE-3188.patch, TestIndexSplitter.java
>
>
> When using the method IndexSplitter.split(File destDir, String[] segs) from
> the Lucene cotrib directory (contrib/misc/src/java/org/apache/lucene/index)
> it creates an index with segments descriptor file with wrong data. Namely
> wrong is the number representing the name of segment that would be created
> next in this index.
> If some of the segments of the index already has this name this results
> either to impossibility to create new segment or in crating of an corrupted
> segment.
