> Java nowadays is mostly used for business applications, where developer productivity is more important than runtime performance

While both of these things are true, they not connected in the way you imply, since Java is a pretty low level language by today's standards.

In the Java school of business app engineering, writing the code is rarely a big part of the effort, so it doesn't matter if the langugae is not very good or expressive. Java wins at having a big commodity-like labour pool of programmers, and there's a lot of inertia and stability in the platform.

There are of course a lot of people who use more expressive and creative tools in making business apps, like eg the many companies using Clojure, Scala, Ruby, Python etc for them, so it's not the only way to skin the cat.
