Not at all! For instance inegrating into VAJ there is just one VM for
developing AND running ANT. I think it is similar in other IDEs. This is the
reason why Wolf Siberski and I developed the GUI for the ANT VAJ
tool-integration using AWT and not SWING - to be independent of the VM used
by the IDE!

HPUX 10.20. HP *will not* port Java 1.2 to that platform due to a broken
threading model (my uninformed analysis). You'd be surprised how many
people are stuck there and won't upgrade due the involved costs and
political issues (two of my customers are in this situation).
I just wanted to drop in this data point. Personally, I'm in the camp
that post Ant 1.3 we should make full use of Java 1.2 features and
require that platform as a minimum. I think Ant 1.3 would be perfectly
sufficient for people standed on the Java 1.1.x platform, myself being
one of them.

What environment would that be? I don't know of any environment that
doesn't have reasonable 1.2 support. Hell - excepting *BSD, I don't know of
any developers environment that has a 1.2 but doesn't have a reasonable 1.3.

inclusive is good ... when it is not limiting. If I had to choose between
keeping 100% of current user base or developing a better product (and thus
more likely gain more more users) you know which choice I would make ? ;P
If you *reall* want 1.1 then you always have 1.*

However, you can have both JVM's installed on your machine at the same time
and given the fact that 1.1 code runs fine on 1.2 JVM's this would be a
great migration path.

Jon-
I wasn't confused, and I don't think too many people were. Being able to
build 1.1 code using an Ant that itself only runs in a 1.2 VM doesn't matter
to folks who develop and build their code on systems for which JDK1.2 is
unavailable. You would essentially be telling those folks they can't use
Ant in their development environment, they will have to go find some other
system that has a 1.2 VM available for doing their builds. I don't know how
many systems only have 1.1 VMs available, but I would rather see Ant be
inclusive rather than exclusive. Just my 2 cents as a devoted Ant user.

4) For the people who are still confused and just don't get it, this is the
*build environment* that would have the JDK 1.2 requirement. It doesn't
matter if your code execution still has a JDK 1.1 requirement because you
can still use Ant to compile your 1.1 code.

Undetermined. To be quite honest, there isn't a jdk 1.2 dependency yet in
AntEater that isn't fixable with a bit of work. I'm currently being selfish
and not doing that work. That work being the implementation all the
functionality of URLClassLoader and making sure that the jars created by the
bootstrap code are fully compatible jars with URLClassLoader. It's easy
enough to do this later, but my goals right now are to work on *how*
AntEater works, not every little detail yet.
You'll note that I'm not using Collections which are a harder to rectify
issue. It's too bad really because Collections would be a perfect way to
express some of the connections in the tree model.
I do agree with Jon in that it is probably time to just cut to the chase and
move to 1.2. There is now a JDK 1.2 for every major platform out there.
Even FreeBSD has it now. Even Macs have it with OS X which will be out and
final by the time AntEater is grown up (and is the platform that I'm writing
AntEater on).
To the argument that there's still JDK 1.1 development happening -- a few
comments.
1) JDK 1.3 is out. It's probably time to upgrade. Are you still running
Windows 3.1 in your enterprise? If so, you probably need to get a new job --
I know of lots of places in the valley hiring right now.. :)
2) JDK 1.2 based compilers do generate code that will run on 1.1. Just don't
use those class libs that are not on 1.1.
3) Ant 1.x will always be there for support of JDK 1.1. I'm not sure that it
makes since to burden every future version of Ant with support for 1.1 when
we've already got something that works there.

This will make ant (or the bootstrap, at least) not compatible with 1.1, I
believe. Is that going to be part of Ant 2's charter?
