GitHub user cpoerschke opened a pull request:
https://github.com/apache/lucene-solr/pull/94
select?collapse=... - fix NPE in Collapsing(FieldValue|Score)Collector
https://issues.apache.org/jira/i#browse/SOLR-6510
Patch is against branch_4x where CollapsingQParserPlugin line 230's
searcher.getAtomicReader().getSortedDocValues call could return null. On trunk
the line 230 call has been replaced (by LUCENE-5666) and so the
CollapsingQParserPlugin part of the patch is not required.
The TestCollapseQParserPlugin change could go to branch_4x only or
branch_4x and trunk.
