It depends what you mean by systems outlook but JVM based code is pretty common (to the point I’d say ubiquitous) in large distributed systems.

In open source it’s much the same. Many of the large Apache projects are in JVM languages, for example.

The indirection in Java does drive me crazy. But dependency injection is a problem to solve in every language and libraries that can do code generation at compile time like Dagger2 make this predictable, debuggable, and fairly easy to reason about on the JVM.

Microservices are, in my opinion, more of a business organization solution than one tied to any specific language. If you haven’t read Steve Yegge’s blog post about Amazon vs Google I think it’s good reading on why/when SoA is a good idea.
