I’ve programmed in Scala most days for the past 3 years, we use plenty of Java libraries, and it works well. Generally it’s as simple as a thin wrapper around the library, that converts mutable data classes to immutable versions (or vice versa), and wraps blocking methods in futures. Sometimes it’s more complex than that, but when I’m reaching for a Java lib, normally it’s just for a few methods that are easily wrapped.
