NPE in o.a.g.conn.JCAResourceImpl.getAdminObjects

Hi All, 
 I am getting NPE  while running jconsole. I am not very familiar with this code, but I think the error is due to this code:
public JCAAdminObject[] getAdminObjectInstances() {
        return (JCAAdminObject[]) adminObjects.toArray(new JCAAdminObject[connectionFactories.size()]);
    }

The code should use adminObjects.size() not connectionFactories.size()
return (JCAAdminObject[]) adminObjects.toArray(new JCAAdminObject[connectionFactories.size()]);


thanks
Anita
