I think most do not realy do this 'on purpose'. It's how it works.

Uhhmm.... JBoss Cache?

Funny is that I kind of semi use jBPM in this resource way. I extend the processdefinition with my own xml tags for which I do not develop a specific jpdl parser or whatever. Runtime, I read the xml nodes with xpath from the processdefinition in the processarchive (will show this in the presentation also on the community day)

I'll think about the other thinks though. Not fully grasp all differences yet, but that might be because it is to late (04:00 am)
