DireIce is on a roll.

DireIce, proliferous mapper of JB and other, far less interesting game types, has released JB-Warehouse, a small and relatively simple map for four to eight players. You feedback is welcome in the usual place.

In other DI news, he's released a final of the excellent JB-Darktowers, along with a CTF version. And to top things off, you really should visit his site from time to time for an excellent selection of CTF conversions, original work, and other neat stuff.
