I am not much sure about jBPM 4, but in jBPM 3 code I am using. I can suspend and resume a process by using the following API's on ProcessInstance Class org.jbpm.graph.exe.ProcessInstance | public void suspend() | | suspends this execution. This will make sure that tasks, timers and messages related to this process instance will not show up in database queries. | | public void resume() | | resumes a suspended execution. All timers that have been suspended might fire if the duedate has been passed. If an admin resumes a process instance, the option should be offered to update, remove and create the timers and messages related to this process instance.
