It's a minor update to a version of HotSpot that is _not the default_,
and which fully bootstraps with both normal and Zero builds.  I don't
recall Shark working with hs16 before so how is this a regression?

FWIW, Shark also can't bootstrap itself on 7 either
(http://icedtea.classpath.org/bugzilla/show_bug.cgi?id=348) and that's
been the case for some time.  If I thought there was going to be a fix
for this in the next week or so, I would see the point in delaying the
release.   Are you offering to fix this?

As is, I don't see how there is anything to gain from waiting
indefinitely for a fix to a pretty minor build option (hs16+shark).
Shark is still a work-in-progress and anyone wanting to ship
Shark+hs16 binaries would be quite mad.

As I said before, I've updated hs16 because if we're going to include
the option to build with it at all, we should use the same version Sun
are shipping and that will end up in b18.

What other bootstrap compilers?  Other than the arch., that sounds
pretty much like what I did.
