I just published a new snapshot at https://repository.apache.org/content/repositories/snapshots/org/apache/optiq/, based on https://github.com/apache/incubator-optiq/commit/771ec5449a0e8cea1f2a55626b9850b64a5a4937.
It includes https://issues.apache.org/jira/browse/OPTIQ-396 and https://issues.apache.org/jira/browse/OPTIQ-398, so a few methods have moved around. Julian
