I have a requirement to start a timer when a process instance begins, and if the process does not go to an end-state within a stipulated time, the timer is to bring the process instance to a premature end.

Can this be done at all? So far I have experimented with doing

executionContext.getToken().setNode("end node");

at MyTimerActionHandler.execute() method, but it doesn't work. I get a hibernate exception during persistence of the jbpm context.

any help?
