Regarding the zinc-java output bug in zinc 1.0.5: With tip of trunk pants and zinc 1.0.4 & 1.0.5 (the current release version) the warning and error output is incomplete. With tip of trunk pants and zinc 1.0.2 (the current version we are using) all output from the compiler disappears. That rules out using a recent release of Pants with the zinc-java compile. We don't have to gate the release on fixing the problem with zinc output and java compilation, but keep in mind that Twitter and Square both use zinc-java compilation now. We'll either have to 1) back down to jmake (slower) or 2) skip updating to a new version of pants until this is fixed.
