Thanks Gary, I think your analysis and your conclusions make sense. I noticed the DB API change when we were trying to debug this problem, but the change seemed a bit too large for RC1. It makes sense now doing it in Havana, and perhabs backporting to stable/grizzly.
Thanks again for tackling this issue.
