[dev oct 03] After using a dev build with the Node.getLookup change and the metrics module installed, I found that trying to open the Tools menu throws a bunch of CCE's from properties module each time, making the IDE unusable until you disable either metrics or properties. Looking at the code, it is clearly wrong - equals() can be called on any Object param, even of different type, and you must consider that - though I can see why the problem would only appear now: ItemElem is now a cookie, meaning it is dumped into a Lookup with other cookies.
