At the moment we're not automatically generating full source tarballs,
but you can get a tarball of each tree in the Jigsaw forest by using one
of the handy "bz2", "zip", or "gz" links at the top of each tree's hg
page, i.e.,

    for t in . corba hotspot jaxp jaxws jdk langtools; do
      wget http://hg.openjdk.java.net/jigsaw/jigsaw/$t/archive/tip.tar.bz2 \
        -O ${t/./root}.tbz
    done

(You'd have to do a little bit more scripting in order to untar these
 into a buildable forest.)

We're definitely interested in any feedback resulting from such an
investigation!

Once Jigsaw is integrated into the mainline JDK 7 code base then you'll
be able to get it just by fetching the regular JDK 7 source tarballs [1].

The plan is -- still -- that Jigsaw will be in JDK 7.
