Yes, we in fact should be getting our dependencies right, however,
with the demo/sample stuff, coming up
with the correct dependencies may not help much, it might always get
rebuilt most of the time anyway. :^(
I had hoped to someday (or hoped someone would) pull all the demo/
sample code from the jdk repository
and create a separate repository for all the sample/demo code. Maybe a
sub repo of the primary forest and
allow for a separate schedule where they could be improved and added-
to without being constrained by the
primary jdk product as much? Just an idea. It would simplify the jdk
build process too of course.
