Works for me, but them I'm using recent and you're using something of 1yr ago. Suggest you debug it, or use a recent version

Could you be so kind and try it with the version I defined in the pom?

Why should I use 2.2.0.m1? it's no longer supported

No offence Andy, you do great work here, but it would have been nice to know that you're not going to run the test-case against 2.x before you asked me to create one.

Jan, no offence taken.
The docs state very clearly what version(s) are maintained/supported ... free and commercial, http://www.datanucleus.org/products/accessplatform.html
The forum README says to use nightly builds. The resource of this project is such that I will typically be working on latest code only (except during the phase of starting a new major release, when I'd maintain the previous for limited time).
Consequently it ought to have been easily concludable that I would run any testcase on the version I am maintaining (only), and I did just that. Needless to say that other people could offer their time to maintain old versions.

Obviously you could go through the same process with Hibernate (with their 20+ devs) and you won't even get it run on any version, to add to the 2500+ issues :-)
