How do I convert clojure.lang.ArraySeq to a Java String[]?

I have a Java class with a constructor taking a variable number of String arguments like this:

public Foo(String...args);

I'm trying to create a make-foo multimethod in Clojure to handle this:

(defmethod make-foo clojure.lang.ArraySeq [& args] (new Foo (into-array args)))

But when I call it with

(make-foo ["one" "two"])

I get: IllegalArgumentException No matching ctor found

I'd also like to be able to call it with

(make-foo '("one" "two"))

I see there are to-array variants for ints, floats, etc, but no String. So how do I handle this case?

make-foo as written would work if you called it like (make-foo "one" "two"), or you could remove the & from its definition and then pass it sequences.
