---------------------------------------------------------------------
I don't think your approach is covered by the aries jpa project. So please use
jpa 2.0 and the blueprint jpa support or wait till aries officially supports
jpa 2.1. Building the EntityManager by hand can work but it will be difficult
to get this right.
Btw. Why do you need jpa 2.1?
