Implementing async/await. You can accomplish that entirely via macros in Common Lisp, whereas in Java you would need to do bytecode transformation via a javaagent (which, shockingly, I just discovered somebody has actually done: https://github.com/electronicarts/ea-async).

That being said, I write Java for a living, and I don't find it terribly verbose, outside of the lack of sum types, pattern matching, and typeclasses.
