[jira] Closed: (DIREVE-88) Single level search request on leaf node causes a Nullpointer exception
Posted by "Alex Karasulu (JIRA)" <di...@incubator.apache.org>.
[ http://nagoya.apache.org/jira/browse/DIREVE-88?page=history ]
Alex Karasulu closed DIREVE-88:
-------------------------------
Resolution: Fixed
Fixed in revision 106725 here:
https://svn.apache.org/viewcvs.cgi?rev=106725&view=rev
Basically when the underlying list returned from ctx.search had no more elements the prefetched value in the SearchResponseIterator wrapper was returning a null reponse object. This was causing the NPE. However this was not effecting the return of the next SearchResponseDone response. So it was working. By checking if the list returned from ctx.search().hasMore and returning a singleton iterator if it is empty we eliminated this problem.
