Assuming the code is self contained and isolated from bootstrap.bat/sh, 
we can have optional version code in the system, sorry if that was an 
issue before.

Having had a look at hotswap, I dont know whether to be impressed or 
scared. Are you using this for hot deployment to a live system, wow. Not 
in production, one would hope.

At the very least we can link to it on the web site, it is a very wild 
idea. As to whether we'd want it in the core (putting aside the fact 
that you'd need to add an apache-compatible license ), I am scared of 
its powers. Only to be used in the hands of the competent, i think. But 
its potentially no worse than any normal debugger. And it is certainly a 
task closely related to the build/deploy process.

So I will ask other people to give their opinion.

Looks cool... BTW you may be interested to know that NetBeans 4.0 uses a 
similar task to do hotswapping during debugging:

http://www.netbeans.org/source/browse/~checkout~/debuggerjpda/ant/antsrc/org/netbeans/modules/debugger/jpda/ant/JPDAReload.java?content-type=text/plain

This task however makes use of some IDE-specific calls for various reasons.

Just wondering if anyone else has any thoughts on the <hotswap> target, 
feel free to look at the web page (http://hotswap.dev.java.net/) and 
read Steve's comments below.
Thanks!

When you say "scared", I hope the code didn't look that bad! (I mean, I thought
you might be talking about the power it could unleash).
No, we don't use it for production at all. Yes, we use it for development only.
I like that I can edit in Vim and invoke an ant target to compile and hotswap
my changes into the app. When I don't actually need a debugger and don't want
to fire up Eclipse, I use this instead.
I'd be happy to attach whatever license is required.
