Everything is technically possible ;-)

I was thinking of using language="bsh:javascript" or "jsr:javascript"
to allow the
user to force one or the other, however, having bsf.jar and js.jar in
the $ANT_HOME/lib, is a user's choice, so if they are there it is
a good assumption that the user wants to use them.
