Any different if I do it this way? (Use blank SyncWSHumanTaskHandler constructor)
SyncWSHumanTaskHandler syncWSHumanTaskHandler = new SyncWSHumanTaskHandler();
syncWSHumanTaskHandler.setLocal(true);
syncWSHumanTaskHandler.setClient(localTaskService);
ksession.getWorkItemManager().registerWorkItemHandler("Human Task", syncWSHumanTaskHandler);
