Jason Gerlowski commented on SOLR-13318:
----------------------------------------
Yes, I'd like to backport to 7.7.2 but ran out of time last night. If I have
time after work today I'm still aiming for 7.7.2, as long as there's not an RC
or a freeze before then.

> JsonFacetingResponse and its series of dependent classes hold a variety of
> count fields for bucket counts and various optional properties
> ({{allBuckets}}, {{numBuckets}}, etc.). Currently, some of the code that
> parses these values out of the originating NamedList either stores or casts
> the values as ints. When doc counts are low this works fine. But when the
> doc counts become larger and stray into "long" territory, SolrJ is liable to
> blow up with ClassCastExceptions.
> A user on the list reported on of these with the partial stack trace:
> {code}
> Caused by: java.lang.ClassCastException: java.lang.Long cannot be cast to
> java.lang.Integer
> at
> org.apache.solr.client.solrj.response.json.NestableJsonFacet.<init>(NestableJsonFacet.java:52)

> org.apache.solr.client.solrj.response.QueryResponse.extractJsonFacetingInfo(QueryResponse.java:200)
> at
> org.apache.solr.client.solrj.response.QueryResponse.getJsonFacetingResponse(QueryResponse.java:571)
> {code}
> We should fix this so that these classes can be used without incident for any
> doc counts.
