It only interoperates with Java in a trivial sense. Using Hibernate for example is a real pain in the ass in Scala, because of its insistence on using its own collections.

It's not in a "trivial sense". You can call any Java code from Scala, call Scala code from Java (except when dealing with Scala constructs that don't have direct Java equivalents). Even Java and Scala functions are the same since Java 8/Scala 2.12. I am not sure how much more interoperability you could even wish again, besides saying that Scala should be identical to Scala. And I write this having written Scala for 10 years and used dozens of Java libraries in Scala projects.

This reads like Scala is somehow doing this stubbornly against all reasonable arguments. That's not the case. Scala collections have benefits. Maybe this means using Hibernate is not straightforward from Scala. Ok. I don't know. But this doesn't invalidate Scala having its own collections.
There are tradeoffs in everything. We are talking about two languages and how they interoperate. As far as language integrations go, the Java-Scala interop is excellent, in my view.
