                 Key: SPARK-56305
                 URL: https://issues.apache.org/jira/browse/SPARK-56305

          Issue Type: Bug
          Components: SQL
    Affects Versions: 4.2.0
            Reporter: Stefan Kandic


PivotFirst ignores string collation, causing incorrect NULLs. Fix uses TreeMap for non-binary-stable collations.
