Is there a cats-effect or ZIO for Java? If not, then what are the blockers of having an effect system as of Java 17? What are the drawbacks of such a library in Java?

  ZIO — A type-safe, composable library for async and concurrent programming in Scala

  

ZIO on the other hand doesn't rely on those concepts, so I guess it could be possible ? But I'm not too sure the code would look great without Scala's for-comprehensions and there may be other blockers... By the way there's been some work done in ZIO to provide a Java facade : https://github.com/zio/zio/pull/383. Not sure the interop on that would work so great tbh.
