I think setting the super process token in the createSubProcessInstance causing this issue. Even if i do not call createSubProcessInstance and  I create sub process instance using +*newProcessInstance(processName)*+ and** then if i set the super processtoken explicitly in my code i get this error, if i do not set the super process token in my code i do not get this error. Please provide views, i am getting this error again and again.
