Hmm, I use testing..

ant is a shell-script; it does its best to look for java. It uses JAVACMD, 
or JAVA_HOME if it can't find a java in the path.
I'm not sure this answers your concerns though, and still expects a fully 
implemented JVM.

That is something they can't do; they can call jikes from the command line; 
but that is a LOT slower then ant with jikes, or ant with javac. This is 
because a) ant knows which 'clusters' of files have changed and passes 
them all to the compiler in one compile-run, and  b) ant can do dependency 
checking (which file needs a recompile because it depends on a changed 
one) by reading the class files.
