> "IndexReader is closed" regression in highlighter

> Key: LUCENE-9443
> URL: https://issues.apache.org/jira/browse/LUCENE-9443
> Project: Lucene - Core
> Issue Type: Bug
> Components: modules/highlighter
> Affects Versions: 8.6
> Reporter: Chris Beer
> Assignee: David Smiley
> Priority: Major
>
> I'm seeing a regression the UnifiedHighlighter (observed in Solr 8.6, leading
> to a crashed core), likely caused by LUCENE-9376
> ([https://github.com/apache/lucene-solr/commit/8e578b4e51cbab206c31653077ce4a3e3a6879b8#diff-f545e503a21f7331f0706fb89f7c663eR648?)]
> [~dsmiley] adds: [the] call to close indexReaderWithTermVecCache but this is
> a wrapper IndexReader that is not supposed to be closed. It'll close the
> underlying real reader if you do which is nasty as that's the live one, which
> thus brings down the core.
> This is reproducible with Solr 8.6, a trivial configuration
> ([https://gist.github.com/cbeer/6d3191918b39e3e83e80ac48c00de925),] and an
> empty index with a request like:
> http://127.0.0.1:8983/solr/blacklight-core/select?q=id:[*+TO+*]&hl=true&hl.fl=full_text_search_en+full_text_search_pt&hl.offsetSource=postings_with_term_vectors&hl.method=unified
