they're not looking for a fast language in isolation, they're looking for a fast language in the broader context of their existing technological stacks. Java doesn't help that much when you're looking into ways to speed up your Ruby application, at least not easily.
Furthermore, Java has the issues that it's only fast when memory is plentiful and it has a long startup/running time, it's "eventually fast" if you will.
