Yes but it also has a package manager and library repository with over 5000 idiomatic Clojure libraries. A lot of projects would not even have to use Java libraries.
For someone already familiar with the Java ecosystem, this can be a huge boon. For someone unfamiliar with Java and the Java ecosystem it can be a little bit daunting.
Case in point, I recently had an experience where I was trying to read some binary data with nio. This meant I was reading java docs related to nio trying to figure out a java implementation of what I needed to do. Then I needed to translate this into clojure. As a new clojure user who didn't have quite the grasp of the java interop idioms, my code looked pretty ugly, and with a lot of (. foo (. bar (. baz))) looking stuff.
That said, if you're going to have a "problem," a preponderance of usable, high-quality libraries isn't exactly the worst I can think of...
