Thank you, Andy, for this information! I have upgraded to DataNucleus plugin 2.0.0-RC2 which solves the issue in my development environment. Can I use this version (RC2) in the GAE production environment as well? Can I use the same deployment procedure from within Eclipse as with the DataNucleus plugin bundled with the GAE SDK?
