The big issue with java1.1 is the many introspection hoops we have to jump
through in the code to so things. Even simple things like copying timestamps
when copying files. This affects you: things are slow. It affects the ant
dev team as (a) we have more maintenance work and (b) new tasks are still
constrained to be 1.1 compliant. And thats what you dont see: the suffering
we have to do, for a few people that may still want to run ant on java1.1

Moving to v1.2 gives us collections, security that lets us finally catch
system.exit() is non-forked <java>, significantly better classloading and
other things that most java developers take for granted.

Java1.3 adds very little.
Java1.4 gives us assertions, which are nice but not critical.

Lots of systems still only have Java1.2; we are not looking at moving to
later versions because Java1.2+ support is a lot easier than the special
cases for 1.1.
