I am not sure about your configuration, but the internals of getGraphSession as as follows:

  |   public GraphSession getGraphSession()
  |   {
  |     PersistenceService persistenceService = getPersistenceService();
  |     return (persistenceService != null ? persistenceService.getGraphSession() : null);
  |   }

I would imagine your root cause is because getPersistenceService is returning null.

Check to make sure you have something like the following in your jbpm configuration file.

  | <service name="persistence" factory="org.jbpm.persistence.jta.JtaDbPersistenceServiceFactory" />
