Hi Johannes,
clearly a bug somewhere in the code. So I created bugzilla entries 246533, 246534 and 246535 to track various of the
issues in this problems. 246534 is of most interest for you.
There is currently no plan for a configurable factory. Sounds like a good plan. Please open a bugzilla entry to track
that feature request.

I have explained it in detail in 246534. So just for reference. Jodatime does not work with Hessian in many ways. So
Riena cannot fix these problems and WONT. Sorry about that, but the problem is in the way Jodatime is implemented, as
explained in bugzilla.....
