It must be underscored that this is a _potential_ speed gain. We
actually are not certain what speed gains, if any, we will have.
If we are honest with ourselves, a second and quite powerful motive is
our desire to get Eclipse into main, and that really only serves a
handful of the Debian community at large. All of the Debian policy and
developer docs encourage us to not just think about our packages, but
about the whole project. Is this really something that reflects good
stewardship on our part? I think we have to think that one over.

Approach b) is the only one that seems feasible, and I would only
recommend doing it on a few packages experimentally to see if the
hoped-for speed gains merit the considerable increase in resource
impact. A third option I would also posit is:
c) Take a deep, hard look at what is broken with JIT in the free
runtimes right now and how we could significantly contribute to that
part of free java that really needs help.
Iterpreted languages hardly need me to back them up, but I think they
have a proven track record. Taking one of the leading interpreted
languages and choosing to make its use of native compiled binaries as a
de facto for our distro just doesn't sit well with me.
