True, but you don't develop that way using graal. You develop java apps the usual way (eclipse, emacs/vim/maven, whatever) and create a fat jar (or uberjar). When you make sure the application is working, compile it with graal, creating a static binary.

Clojure cycle is even faster because you keep REPL open and evaluate code directly while application is running. After that, you build uberjar, then compile it with graal.
