Love it or hate it, Java's back catalog of libraries is gargantuan. One of the biggest obstacles in getting a new language adopted is library support. The fact that Clojure gets all that for free is a way to get people using the language now. As Clojure matures, I'm certain more and more native libraries will emerge negating a lot of the need for Java.
I absolutely agree, but if you have no choice but to cooperate with the usual "enterprise" hodgepodge with its myriads of standards and protocols, not having to write something that will allow you to do that, is a huge benefit.
You'll have to suffer the environment, you don't have to suffer the language.
But I think it's going to be interesting whether the clojure community will re-write the innards of the libraries they're wrapping already. Will we see e.g. compojure that's turtles all the way down?
