Are there, or have there been Haskell ports to the JVM? Are any of them alive and well?

Is there an interest in hosting GHC on the JVM (besides my own).

I know I don't have time to tackle such a project but I'd be extremely interested in using such a thing. Especially in my day to day work. I currently do a lot of Java <-> Erlang via JInterface, and have been for months, yet there's many tasks I could do better in a language like Haskell.
