Does he actually need a real arraylist, or will something fulfilling a 
collection interface (Collection, Iterable, or List for example) be ok? Many 
clojure types do not require any casting at all as long as the java code writes 
to a collection interface and doesn't expect to be able to mutate the object. 
(Both of these are good Java idioms: write to interfaces not classes, and copy 
defensively.)

So if your coworkers code just needs something iterable (for example), you may 
not need to do any casting at all: just give him the vector.

If your coworker's code needs a real ArrayList and can accept no substitutes, 
(java.util.ArrayList. your-vector) will make an ArrayList copy of a vector's 
contents.
