Once you get used to working in Java (and have a relatively stable toolchain you can depend on), it's realistic to develop applications in Java almost as quickly as Clojure, though complex aggregations that Clojure makes one-liners will often be vastly slower to develop. IntelliJ makes a lot of things easier as well. When it comes to Java, you just need to really get familiar with your tools before you can be as productive, but once you are you can move quickly. Using Java 8 doesn't hurt either, streams are pretty decent.
