Description
This is a very weird problem that is reproducible on a small production server, but not on the local machine although they run the same 6.0 version., and have an almost identical index. The only minor difference is that production is a SolrCloud with 1 shard and two replica's, just for a bit of redundancy.
The following query yields zero results and throws the NPE:
select?q=query:seis&fq={!collapse field=query_digest}&fq={!collapse field=result_digest}
The next query does yield results and does not throw anything, it just works as it should work:
select?q=query:seiz&fq={!collapse field=query_digest}&fq={!collapse field=result_digest}
The /select handler used does not add any fancy param other than rows.
Here's the NPE:

Edit: for the sake of clarity. It really needs double fq={!collapse bla bla for the NPE to appear. If i remove either of the filters from the query, i get a nice zero resultset back. Both fields are defined as int.
