My understanding is that Class.forName uses the "current loader" - i.e. the
defining loader for the class - which for most tasks is the main
AntClassLoader. So far using the ClassLoader task ( which just adds jars
to the main loader ) seems to work fine and never run into any problem with
Class.forName not finding something. 

I would also add the JBoss class loading scheme - which is also adding jars,
with few twists to support reloading - is also working fine with

( yes, I know I need to write the docs for the loader task - this is the 
first thing I'll do after I finish with the current tasks ).
