-------------------------------------
any Objections? Uwe you still want to take this or should I?
I want to get LUCENE-3012 wrapped up.

> Key: LUCENE-3014
> URL: https://issues.apache.org/jira/browse/LUCENE-3014
> Project: Lucene - Java
> Issue Type: Task
> Reporter: Robert Muir
> Assignee: Uwe Schindler
> Priority: Critical
> Fix For: 3.2

> Attachments: LUCENE-3014.patch

> See LUCENE-3012 for an example.
> Things get ugly if you want to use SegmentInfo.getVersion()
> For example, what if we committed my patch, release 3.2, but later released 3.1.1 (will "3.1.1" this be whats written and returned by this function?)
> Then suddenly we broke the index format because we are using Strings here without a reasonable comparator API.
> In this case one should be able to compute if the version is < 3.2 safely.
> If we don't do this, and we rely upon this version information internally in lucene, I think we are going to break something.
