SOLR-7781: change FacetField BytesRef shallow clone to deep clone
> FieldFaceting BytesRef reuse bug
> --------------------------------
>
> Key: SOLR-7781
> URL: https://issues.apache.org/jira/browse/SOLR-7781
> Project: Solr
> Issue Type: Bug
> Components: Facet Module
> Affects Versions: 5.1
> Reporter: Yonik Seeley
> Assignee: Yonik Seeley
> Fix For: 5.3
>
> Attachments: SOLR-7781.patch
>
>
> FieldFaceting on a string field has
> {code}
> new TermQuery( new Term(field, bytesRef.clone() ) )
> {code}
> The bytesRef needs to be deep copied (and clone() only implements a shallow
> copy).
> This causes to the query inserted into the filter cache to be changed after
> the fact, and causes both cache misses and even cache growth way past
> configured limits due to failures to remove old cache items (SOLR-7777).
