Issue can be reproduced (quite often) on the _techproducts_ example collection with the following query :
{noformat}
http://localhost:8983/solr/techproducts/select?q=*:*&wt=json&indent=true&facet=true&facet.query={!tag=q1}manufacturedate_dt:[2006-01-01T00:00:00Z%20TO%20NOW]&facet.query={!tag=q1}price:[0%20TO%20100]%20&timeAllowed=1

> ClassCastException in SearchHandler
> -----------------------------------
>
> Key: SOLR-8851
> URL: https://issues.apache.org/jira/browse/SOLR-8851
> 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(SearchHandler.java:293)
> at org.apache.solr.handler.RequestHandlerBase.handleRequest(RequestHandlerBase.java:156)
> ...{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.
