Thanks Alejandro for your prompt reply. Yes you are correct that subprocess instance automatically sets the superprocess token. In my case if either I set the superprocess token or i use the 'createSubProcessInstance' to create the subprocess which automatically sets the super process token i get this error. Please have a look at the following code snippet, I am using in my work flow:


public void execute(ExecutionContext executionContext) throws Exception {

            processName = getProcessName();
                               
            ProcessDefinition processDefinition = ManagedJbpmContext.instance().getGraphSession().findLatestProcessDefinition(processName);
            ProcessInstance pi = executionContext.getToken().createSubProcessInstance(processDefinition);
          Task task = ProcessUtil.getStartTask(pi.getProcessDefinition());


            Map<String, Object> values = extractCallerData(executionContext,
                    task);
            TaskInstance ti = ProcessUtil.initializeProcess(pi, task, values,
                    false);

            if (ti != null) {
                // setup the swimlane instance
                Swimlane s = ti.getTask().getSwimlane();
                if (s != null) {
                    String assignment = s.getPooledActorsExpression();
                    if (!Strings.isEmpty(assignment)) {
                        ti.getSwimlaneInstance().setPooledActors(
                                assignment.split(","));
                    }

                    ti.end();
                }
            }
}
