Little but not negligible: a JsArray has a varying length.

It would add overhead only in Hosted Mode, as you can use a
"reinterpretCast" in Web Mode with no overhead at all. It's been
discussed several times on the list and you can find an example
(actually, a library) at http://code.google.com/p/gwt-in-the-air (in
