It is. This is the list where development of Ant itself is discussed
and what you want might require a change to Ant, so you meet the right
people here.

We are talking about the non-forked execution of tha java and junit
tasks only, right?

Many if not most tasks haven't been written with extension in mind,
I'm not surprised that you don't find a clean extension point.

[I'm talking about Ant's svn trunk version since we'd only make
changes there anyway]
Since we are only talking about the non-forked version, you'd probably
rather override run(CommandlineJava) - which is private - or somehow
make the task use a subclass of ExcecuteJava of yours. ExecuteJava
creates an AntClassLoader internally, so you probably need to modify
it yourself.
I see options of making run() protected or factor out the line
ExecuteJava exe = new ExecuteJava();
into a protected method that you could override. I'd prefer the
second version.

Please check whether it still works with Ant's current svn trunk
version since Ant 1.7.0 using that code is coming around pretty soon.
