For the binary distribution we have to set the FINAL flag to a production
value. But when the user takes the source he/she can then compile jBoss
to what they like or need. I don't know how much we gain but without the
final flag you can never figure it out.
It also would help to add more logging than just for production and direct
this through the final flag.
