How PVM is related with JBPM

[dinosaurus]

Hello,

I'd like to know how PVM and JBPM are related together:
- Do they share same database tables?
- Does JBPM use PVM inside? From which version?
Which features it adds on top?
I appreciated a lot for any info on the mentioned above questions.

Thanks in advance
