Chris M. Hostetter updated SOLR-18156:
--------------------------------------
Attachment: SOLR-18156.patch
Assignee: Chris M. Hostetter
Status: Open (was: Open)
Patch with a suggested fix (override {{searchLeaf}} instead and move the custom
logic into it)
This also includes randomized usage of {{timeAllowed}} in {{testJoin}} to
demonstrate the problem if the patch is not in place...

> Beginning with Solr 10.0.0, attempting to use any of the {{join}} QParsers in
> conjunction with QueryLimits results in a ClassCastException.
> This is because {{JoinQuery.createWeight(...)}} expects it will only ever be
> called with a {{{}SolrIndexSearcher{}}}, but
> {{SolrIndexSearcher.seach(Query,Collector)}} is overriddent to create an
> anonymous {{IndexSearcher}} to use when QueryLimits are enabled.
> This was not a problem in Solr 9.x, because back then the logic for creating
> an anonymous {{IndexSearcher}} was inside the overridden
> {{SolrIndexSearcher.seach(List<LeafReaderContext>,Weight,Collector)}} (after
> the {{Weight}} instance had already been created using the original
> {{{}SolrIndexSearcher{}}})
