I was not aware that D and Lua had the JVM as targets.

You only asked for non-FP languages, not non-FP languages with the JVM as a target. There's a Lua implementation for the JVM called kahlua. It appears to be in a fairly early stage of development and may not be fast or suitable for production use. As far as I know, there is not a D compiler for the JVM.

Groovy appears to be potentially as fast as Java. It can call Java easily, which means you always have the option to rewrite something that's too slow in Java itself.

Thanks again. Apologies if my terseness meant a loss in clarity. I thought the JVM was implicit in the thread and that you were listing languages with the JVM as targets (also my mistake as I see that you were not exclusively listing those, guess I should refrain from posting till I've had more sleep).
