In case my meaning did not seep through my sudden outpouring of prose
(triggered by Woof! with apologies to Mardy):


Many/most java projects on which we have dependencies are not
releasing RPMs. Until at least that time I agree with your and Mardy's
conclusion. It is attractive to work towards a pristine distribution
as this means we have a shot at being included in a linux distro but
may not be feasible for a while yet. So long as we have to include at
least one jar file, we cannot have a pristine distribution and hence
we should just distribute jars the way we do now rather than fight
that fire when the fire cannot be extinguished at the moment.
