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.
