Oh, and the openoffice.org web site has not been moved under ASF custody yet. So a lot of material there is now obsolete, especially around licensing and code donations.

As someone else is mentioning, the Apache Contributor License Agreement is not a copyright transfer. It is a license only. Also, Oracle did not transfer the copyright on OO.o to the Apache Software Foundation - they licensed the OO.o code base to Apache in a way that allows Apache to release it and their derivatives under the Apache License.

Also, at the ASF forking is a feature. There is no problem with forks, even of the Apache Licensed version, so long as in that case the Apache License and applicable trademarks are honored.
