Not really. Clojure has nice native syntax for Java interop (or JavaScript for ClojureScript). In fact, I'll occasionally use Clojure to explore a Java API while working in Java. What happens in my experience is that Clojure programs do tend to encapsulate more extensive use of Java interop into their own modules. For more standard or commonly used packages, this means a canned library or similar. (But this notion of abstracting out APIs is just good software engineering in general, and not really specific to Clojure or anything else.)
