Markus Jelsma commented on SOLR-7435:
-------------------------------------
Ok, this is madness. For some funky reason the following test actually works!
{code}
@Test
public void testSOLR7435() throws Exception {
String[] doc = {"id","1", "a_i", "1", "b_i", "1"};
assertU(adoc(doc));
String[] doc1 = {"id","2", "a_i", "1", "b_i", "2"};
assertU(adoc(doc1));
String[] doc2 = {"id","3", "a_i", "2", "b_i", "3"};
assertU(adoc(doc2));
String[] doc3 = {"id","4", "a_i", "3", "b_i", "3"};
assertU(adoc(doc3));
assertU(commit());
ModifiableSolrParams params = new ModifiableSolrParams();
params.add("q", "*:*");
params.add("fq", "{!collapse field=a_i}");
params.add("fq", "{!collapse field=b_i}");
assertQ(req(params, "indent", "on"), "*[count(//doc)=0]");
}
{code}
I would expect the same NPE but i get the proper output:
{code}
