Is that working for you right now?

I see the same error. I debugged the classes and found out that 
try {
            final ServiceSelector selectors = (ServiceSelector)
super.m_manager.lookup(Selector.ROLE + "Selector");
            m_selector = (Selector) selectors.select(m_type);
        } catch (ServiceException e) {
            final String message = "Unable to get Selector of type " +
m_type;
            throw new ConfigurationException(message,e);
        }
in SelectNode.java is the throwing source. 

Caused by:

I am looking into it. Any hints or tips?
