Hi,

For what it's worth, at Tweag we've developed some preliminary bindings to Apache Spark, and as part of this we developed a somewhat decent API for calling Java. You can check it out on hackage [1] and on github [2]. In cast that can save you some time or inspire you.

Hi Haskell-Cafe,

I've been working on a JVM backend for GHC [1] and I took some time to flesh out a design for the Java FFI [2] which will pretty much decide whether the project will be useful or not. I would love feedback from the community on how to improve the design or requests for important interop features that I have neglected.

Thanks,
Rahul Muttineni
