I solved all of these problems by making sure I didn't outject in BusienssProcessScope anything that wasn't serializable. It appears the functionality exists for JBPM to not try to persist non-serializable variables but it also appears that seam is going around this functionality when outjected BP process variables are inserted into the BP.
