--------------------------------

             Summary: investigate re-adding unwrapSingleton optimization attempted by LUCENE-7643
                 Key: LUCENE-7649
                 URL: https://issues.apache.org/jira/browse/LUCENE-7649
             Project: Lucene - Core
          Issue Type: Improvement
            Reporter: Hoss Man
            Assignee: Adrien Grand


as part of some refactoring done in LUCENE-7643, an optimization for was introduced for some single valued cases, which introduced an NPE risk surfaced in SOLR-10013.

I plan to fix SOLR-10013 by disabling this optimization with a comment pointing to this issue, and commit with it a lucene level  test steve wrote that _usualy_ fails with the optimized code (since it doesn't fail 100% of the time, it suggests the failure is related to the RandomizedIndexWriter - the docs and queries are fixed)
