Steve Rowe commented on LUCENE-5481:
------------------------------------
[~mikemccand], looks like this can be re-resolved, now that you've backported
to lucene_solr_4_7 branch?
> IndexWriter.forceMerge may run unneeded merges

> Project: Lucene - Core
> Issue Type: Bug

>
> I was running some tests and was surprised that {{IndexWriter.forceMerge}}
> caused the index to be merged even when the index contains a single segment
> with no deletions.
> This is due to {{MergePolicy.isMerged}} which always returns false with the
> default configuration although merge policies rely on it to know whether a
> single-segment index should be merged.
