Performance: apis don't allow me to get at listener count to turn off computation for unused node info. My properties window shows LOTS of information which is costly to compute, so since it's not always shown, it's a performance bug in my application that I can't do this on-demand. So while this represents a change in an API and not a bug per se, it's a performance bug that you can't effectively do pull vs. push. See the following nbdev e-mail for motivation (and the thread for background info if needed).

(If you want to keep the method final for performance reasons, perhaps you could add the counter to your own addPropertyChangeListener and removePropertyChangeListeners, and then provide a hasListeners() or numListeners() method. -- Tor
Just reasigning to me.
Required method was added into the org.openide.nodes.Node class. Changes were made so that calling this method hould give raonable results.
