[bv-dev] bv-dev] [BVAL-251] Improve Bean Validation support for modularized environments

It has been a while since I've played around a bit with BVAL-251. I
still think some (standardized) OSGi support would be a good thing.
I've worked on the basic discovery (there are branches for the API [1]
and HV [2]) and I definitely would like to investigate the area a bit
more (would we need special message interpolators etc.), but since
then I just haven't found enough time to continue with the issue. I
hope I can continue with that within the next time. Maybe Kevin has
also some news on that.

Regarding the class loader service, this might be a good idea. I think
we should see which specific use cases there are (which related
problems currently exist etc.) in order to come up with a solution. It
would also be interesting to know how Apache Validation does class
loading. OSGi of course could be an area where such a service might be
very beneficial.
