That's incorrect. Right now I do all my development in Kotlin at my workplace and on the backend. We use Spring (which has native Kotlin support from 5.0 btw: https://spring.io/blog/2017/01/04/introducing-kotlin-support-in-spring-framework-5-0 https://spring.io/blog/2017/01/04/introducing-kotlin-support...) and deploy to a Kubernetes cluster. It is absolute seamless. I'll never write server-side code in Java again if I can help it.
