In my project (AS config migration), I need to keep the results of every config I run with (one per test).

This could be handled in Maven or Ant by creating copies in advance.
But much more ellegant would be to use multiple containers and to let Arq copy some source dir and run AS from there.

For this purpose, I propose to add a config property jbossAsDist and copy it to jbossHome before launching it.
