>             Project: Lucene - Java
>          Issue Type: Bug
>          Components: Index
>    Affects Versions: 2.4.1
>            Reporter: Tim Smith
>
> If you reopen() and IndexReader with a custom setting for TermInfosIndexDivisor, the new segments will not get the old setting for TermInfosIndexDivisor set on the IndexReader opened with IndexReader.open()
> Furthermore, if you call setTermInfosIndexDivisor() on the reopend index, you will likely encounter a IllegalStateException (if any segments were retained from previous index) because the old segments will have already been loaded (and will now throw an exception when trying to set the value)
> Suggest that either the value be propagated to newly opened segments on reopen, or DirectoryReader ignore IllegalStateException from segment readers on setTermInfosIndexDivisor()
