Description
When there is a query timeout in non-distrub mode, SearchHandler is throwing a ClassCastException:
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)
...
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.
