Neil Prosser updated SOLR-2716:

Description:
The hashCode() and equals() methods of a QueryResultKey are dependent on the
order of the filters meaning that potentially identical result sets are missed
when cached.
Query query = new TermQuery(new Term(field1, value1));
Query filter1 = new TermQuery(new Term(field2, value2));
Query filter2 = new TermQuery(new Term(field3, value3));
ListQuery filters1 = new ArrayListQuery();
filters1.add(filter1);
filters1.add(filter2);
ListQuery filters2 = new ArrayListQuery();
filters2.add(filter2);
filters2.add(filter1);
QueryResultKey key1 = new QueryResultKey(query, filters1, null, 0);
QueryResultKey key2 = new QueryResultKey(query, filters2, null, 0);
// Both the following assertions fail
assert key1.equals(key2);
assert key1.hashCode() == key2.hashCode();
