hi , me again, in jBPM, process instance (not system process) , here i understood as,a flow of workflow as per the process definition language 1) Can we have multiple process instances in a execution? 2) Can the process instances, can save the state of itself at any time? 3) Can the process instances be started and stopped during the execution? 4) Can the process Instances communicate with each other? 5) Can i have process instances in different threads and return the status to controlling thread?
