---------------------------------
Reopening the issue as fix is still not merged.
[~uwej711]
I'm not sure if this would make it to 8.3 release. I'm thinking to push the fix
for 8.4, hope that's fine with you.

> Issue Type: Bug
> Security Level: Public(Default Security Level. Issues are Public)
> Components: search
> Affects Versions: 8.2, 8.1.1
> Reporter: Uwe Jäger

> When grouping the results of a query with group.query there is a
> ClassCastException in org.apache.solr.search.Grouping.CommandQuery.finish
> (line 890) since the collector is wrapped in a MultiCollector.
> The wanted topCollector is available in the inner class so it can be used
> directly and the cast is not necessary at all. After that change there are
> still the scores missing in the result, so populating the scores is
> necessary, too.
> I will create a PR showing the error and also containing a fix.
