[SOLR-17268] Solr 9.3-9.6 (JacksonJsonWriter) does not support "json.nl=arrntv"

• Type: Bug
• Status: Open
• Priority: Minor
• Resolution: Unresolved
• Affects Version/s: 9.3, 9.4, 9.5, 9.4.1, 9.6
• Component/s: Response Writers

Description

Asking for facets and using "json.nl=arrntv" results in the exception:

arrntv namedListStyle must only be used with ArrayOfNameTypeValueJSONWriter

• Code inspection shows that ArrayOfNameTypeValueJSONWriter is supported by the older JSONResponseWriter and not by the newer JacksonJsonWriter.
• Running a facet query with "json.nl=arrntv" works for 9.2.0 and 9.2.1
• Running a facet query with "json.nl=arrntv" fails (Exception/500) for 9.3.0 and 9.6.0
• For 9.3.0, using

  <queryResponseWriter name="json" class="solr.JSONResponseWriter" />
  

  in solrconfig.xml is a successful workaround.
