It turns out I missed the 0.17 release, probably because I didn't expect a new release so soon. Rock on, guys! Updated packages are available at the same location as before.
I'm afraid I can't push ('monotone sync' actually) to the OpenEmbedded repository right now, since monotone decided to screw itself over and fail with an invariant violation on 'monotone merge'. If you want to build Classpath 0.17 with OE just rename the .bb: 'mv packages/classpath/classpath_0.16.bb packages/classpath/classpath_0.17.bb'.
