Markus Jelsma commented on SOLR-8851:

I think this duplicates SOLR-7864

>                 Key: SOLR-8851
>                 URL:
>             Project: Solr
>          Issue Type: Bug
>    Affects Versions: 5.4.1
>            Reporter: Pascal Chollet
> When there is a query timeout in non-distrub mode, {{SearchHandler}} is throwing a {{ClassCastException}}:
> {code}java.lang.ClassCastException: org.apache.solr.response.ResultContext cannot be
cast to org.apache.solr.common.SolrDocumentList
> 	at org.apache.solr.handler.component.SearchHandler.handleRequestBody(
> 	at org.apache.solr.handler.RequestHandlerBase.handleRequest(
> 	...{code}
> The problem can be reproduced if any component running after {{QueryComponent}} times
out - in our case it is {{FacetComponent}} which throws a {{ExitingReaderException}}.
> {{SearchHandler:293}} expects a {{SolrDocumentList}} in {{rsp.response}}, but {{QueryComponent}}
did add a {{ResultContext}} instead.
> It looks like this is not a problem, if the {{QueryComponent}} itself is timing out,
as rsp.response is null in that case. It's only a problem if a component after {{QueryComponent}}
is timing out.
