I appreciate the discussion.

There is some critical mass of knowledge you need to understand the persistence aspects of JBPM.  Pulling a GraphSession out of a JbpmContext and calling "save()" could mean anything.  Where does the transaction start and end?  What gets rolled back when you when you call JbpmContext.setRollbackOnly()?  Every API needs a contract, a set of documented rules that defines a model and how the model is affected.  Reverse-engineering it from code is really unproductive except to clarify special cases.  All us newcomers are in the same boat until the developers really document it.
