I'd like to put this on hold until Java 8 is available in Debian stable, not just in backports, and that might still take a couple of months. (If Java 8 had any critical features or fixes that we'd rely on, we could use backports, but it seems that's not the case, so why rush this.) And once Java 8 is in Debian stable we'll have to wait until all projects depending on metrics-lib have upgraded, which may take another month or so. The 2.0.0 milestone seems too optimistic for all this, so I'm removing the milestone for now.
