JBPM 6.3: How to set custom business administrators for tasks

Question

My JBPM system uses LDAP for identity management. Since the user Administrator and the group Administrators are not valid in my environment, I need to set my own group BPMUL-admin as the business administrator for all tasks. According to this answer, I added 'Human Task' work item handler to CustomWorkItemHandlers.conf:

[
  "Log": new org.jbpm.process.instance.impl.demo.SystemOutWorkItemHandler(),
  "WebService": new org.jbpm.process.workitem.webservice.WebServiceWorkItemHandler(ksession),
  "Rest": new org.jbpm.process.workitem.rest.RESTWorkItemHandler(),
  "Service Task" : new org.jbpm.process.workitem.bpmn2.ServiceTaskHandler(ksession),
  "Human Task" : new ru.rshb.kie.LeaHTWorkItemHandler(runtimeManager)
]

drools.session.conf:

drools.workItemHandlers = CustomWorkItemHandlers.conf

And here is LeaHTWorkItemHandler:

public class LeaHTWorkItemHandler extends LocalHTWorkItemHandler {

    public static final String ADMIN_GROUP = "BPMUL-admin";

    public LeaHTWorkItemHandler(RuntimeManager runtimeManager){
        super.setRuntimeManager(runtimeManager);
    }

    @Override
    protected Task createTaskBasedOnWorkItemParams(KieSession session, WorkItem workItem) {
        InternalTask task =(InternalTask)super.createTaskBasedOnWorkItemParams(session,workItem);
        Group adminGroup = TaskModelProvider.getFactory().newGroup();
        ((InternalOrganizationalEntity) adminGroup).setId(ADMIN_GROUP);

        task.getPeopleAssignments().getBusinessAdministrators().add(adminGroup);
        return task;
    }
}

1. When I try to deploy this, I get an error:

Caused by: javax.ejb.EJBException: [Error: no such method or function: runtimeManager] [Near : {... "Human Task" : new ru.rshb.kie.LeaHTWorkItemHandl ....}]

If I delete runtimeManager from the constructor, then I see that the constructor is called, but the method createTaskBasedOnWorkItemParams is never invoked by JBPM.

What am I doing wrong? Or perhaps is there a better way to define custom business administrators?

I use JBPM 6.3.

Ok, I figured it out. I removed my work item handler from CustomWorkItemHandlers.conf and added the following line before I start the process:

ksession.getWorkItemManager().registerWorkItemHandler("Human Task", new LeaHTWorkItemHandler(runtimeManager));
