A sudden concern about invokedynamic

It occurred to me just now there could be a small snag with
invokedynamic. Maybe it's addressed in the spec, but I don't have it
here right now. If it's not a problem, a 5-second explanation would do.
Otherwise, we might want to discuss here, since it's certainly
How would invokedynamic work if we don't have compiled Java bytecode
anywhere to dispatch to? For example, JRuby is mixed mode right now, and
some methods are interpreted (AST or various bytecode specs) while some
methods get compiled to JVM bytecode on-the-fly. For the compiled ones,
invokedynamic would just get a normal method handle. What about for the
interpreted ones? Essentially we want to be able to pass out a method
handle that's actually just a call into the JRuby interpreter.
I don't recall seeing anything in the docs that might show how to do
that. Did I miss something?
