Slightly modified version now up in

     http://cr.openjdk.java.net/~darcy/8205615.5/

* Changed projected ship date in make/autoconf/version-numbers
* Some changes and merges to jdeprscan; I'll ask Stuart to review those

Some hotspot test changes in the work too based on a separate review thread.
