Me too. My top JVM language feature requests lately are (not including
indy, which is well on its way):

1. Interface Injection (I have started to explore what it would take
to remove IRubyObject from all our call paths; it's a *lot* of work)
2. Fixnums (or even better, general-purpose value types...on numeric
algorithms, JRuby is saturating allocation rates right now)
3. Coroutines (ideally without requiring me to annotate every frame
that can be resumed, since in Ruby or Python that could basically be
any method anywhere)

I'd also like to see tail calls, but it doesn't directly help me.
