Maybe I misunderstood the multi-version JAR files proposal, but I thought that the assumption there is that there are actual *source* files which use newer features of the platform. I really don't think this tooling support will provide sufficient enticement to developers to maintain separate 7/8/9 source branches of their libraries. Isn't that the main obstacle, and not the way the bits are delivered? -- Florian Weimer / Red Hat Product Security
