My main point was, at least what I remember of the podcast, Jigsaw and OSGI were pretty much dismissed, and everyone was going on that they wished everything worked like CPAN or Ruby Gems, which to my understanding worked more like how you're saying apt-get works, so we'd only be able to have one version on a server, of say Spring, which seems to nearly delight in making breaking changes between revisions. I'm just trying to see if I'm remembering the 'cast correctly, and if that's REALLY what was being advocated, because it seems like a HUGE step backwards to me. -- You received this message because you are subscribed to the Google Groups "The Java Posse" group.
