top level query executed by the test...
{noformat}
// Can't validate the response, but can check if no errors occur.
simpleQuery("q", "*:*", "rows", 100, "fl", "id," + i1, "group", "true",
"group.query", t1 + ":kings OR " + t1 + ":eggs", "group.limit", 10, "sort", i1
+ " asc, id asc", CommonParams.TIME_ALLOWED, 1);

Line where NPE happens...
{code}
SolrDocumentList docs =
(SolrDocumentList)srsp.getSolrResponse().getResponse().get("response");
String uniqueIdFieldName = rb.req.getSchema().getUniqueKeyField().getName();
for (SolrDocument doc : docs) { // <-- LINE 45
Object id = doc.getFieldValue(uniqueIdFieldName).toString();
ShardDoc shardDoc = rb.resultIds.get(id);
{code}
...so i'm guessing the problem here is that in some situations where
TIME_ALLOWED is exceeded, we can now see processing continue with a null set of
docs in the response?
