No. You can still use xt or saxon ;)

I'm not sure. Technically of course you can do it, but I don't think you can
distribute the resulting work. So when your bootclasspath script modifies the
boot class path, it effectively changes what classes link to each other. The
FSF has a very strong position on it: GPL propagates through class usage. See
the thread starting at
http://www.kaffe.org/pipermail/kaffe/2002-August/040251.html for some
information on different interpretations. As I said, it's up to debian-legal to
figure out whether your bootclasspath scripts don;t violate licenses, IANAL.
