Spring supports everything that helps their bottom line.

Where are the Groovy, Scala, Clojure support nowadays?

[imtringued]

Groovy is still alive within the context of Grails (which is basically a very nice wrapper around Spring) and Micronaut (which is a direct competitor to Spring). Micronaut officially supports Java and Kotlin as well.

I was referring to the way Spring used to sell that they supported those languages, just like they do with Kotlin now.
