One good reason to disallow multiple underscores is to keep multiple underscores available for future language expansion. Presumably JDK7 isn't the last java release to have new language features. I admit I can't think of anything that would be best served by multiple underscores, but who knows what java needs 5 years from now?

so what future language expansion can you possibly foresee happening in the middle of a numeric literal? (which is the only place this single/multiple underscore issue relates to)

It can't be used as a new operator because it is already a valid identifier.
