Liferay. Written in Java. And total crap.
Indeed. A client of $work chose to deploy liferay about 6 years ago. It was glacially slow, a massive resource hog and yet fell over in a faint breeze. They persisted with it for 4 months or so before giving it up as a lost cause. I've no idea how much they squandered on it but expect it wasn't cheap.
If I were in this game for the money I would be a java programmer/publisher. You can apparently write and ship complete dross in java and still people will pay enterprise-level cash for it.
