[jira] [Commented] (SOLR-13318) JsonFacetingResponse classes should
record provide access to count fields as longs
[ https://issues.apache.org/jira/browse/SOLR-13318?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16933427#comment-16933427 ]
Tiago Martinho de Barros commented on SOLR-13318:
-------------------------------------------------
I experienced this issue in 7.7.1 and read in the changelog that it was fixed in 8.1, so I tried the version 8.2 but I still have the same problem. Reading the code, I found that the file {{NestableJsonFacet.java }}(which is part of the patch) was not updated in the source code. It still has a cast to int. Is there a reason for that? Or maybe it was an oversight?

> 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)
> at 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.
