Try cleaning the cache. The newer binding has large changes under the hood to use the BRIDGE / THING structure so if any cache from the old binding is around that may be the cause. I installed it successfully so if anyone else has trouble or success can u post? thanks…

I was able to reproduce this, it happens when you have the JAR in the addons folder already AND then you try to install it from the marketplace without removing the jar from that folder FIRST. Delete the jar from the addons folder and try again and it should work.
