Description

While working on SOLR-5260 I ran across this. It is easily reproducible by indexing techproducts to a two-shard collection and then
&group=true&group.field=manufacturedate_dt

This works fine stand-alone.

When 5260 gets checked in look in DocValuesNotIndexedTest.java for a reference to this JIRA and take out the special processing that avoids this bug for a unit test.
