More importantly, you can use the mature ecosystem around Java (tools, libraries and so on).

Then again, considering the JVM's disastrous recent trajectory (Loom, JPMS, renewed wasted focus on Java-the-language, and so on) that doesn't seem like such a great upside anymore.

Wat? How is the recent trajectory disastrous?

To take Loom as an example..

The primary problem with threads isn't their performance, but the way that they encourage bugs and race conditions by decoupling data access from flow control.

They're fine as a low-level API for implementing a more usable API, but not as the primary API that you expect application developers to use.

Java/the JVM provides a low-level API for threads on top of which abstractions can be built. How do you think clojure implements their parallelism?

And Loom will be absolutely killer feature, it’s not about performance, it’s about blocking. Abstraction built on top of them will be easier to reason about, no callback hell, etc.

This seems to be more of a Java problem, not a JVM problem.
