--------------------------------------
Summary: JsonFacetingResponse classes should record provide
access to count fields as longs
Key: SOLR-13318
URL: https://issues.apache.org/jira/browse/SOLR-13318
Project: Solr
Issue Type: Bug
Security Level: Public (Default Security Level. Issues are Public)
Components: SolrJ
Affects Versions: 7.7.1
Reporter: Jason Gerlowski
Assignee: Jason Gerlowski
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

org.apache.solr.client.solrj.response.json.NestableJsonFacet.<init>(NestableJsonFacet.java:52)

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.
