In fact, after thinking about this a bit more, I'd rather keep the 2.x codebase in trunk parallel to the new Oak components we'll be moving in after 2.6 is branched. This should make it easier to share the code in jcr-commons and other generic components. Having the 2.x and Oak codebases parallel in the same trunk will also make it much easier to implement and test good migration tools. > * Jackrabbit 3.0: Early next year, after the 2.6 and 2.x branches have > been created, we'd replace the current trunk with an Oak-based JCR > implementation. As mentioned above, instead of replacing the trunk entirely, I'd keep both codebases in trunk for now and include *both* the 2.x and Oak repositories in things like jackrabbit-webapp and jackrabbit-standalone, with a configuration option to decide which repository implementation should be used in each particular deployment. Having both codebases included in the same deployment packages will make it easier for downstream users to upgrade to Oak with minimum changes to their deployments. Also things like the backup and migration tools in jackrabbit-standalone should be easy to use also with Oak. With this hybrid approach I'd go first for a stable 2.8 release sometime before summer, with the traditional 2.x repository still the default deployment option but with Oak included as an alternative. Then in unstable 2.9 we can deprecate the 2.x repository and make Oak the default. Finally around the end of the year (or whenever we're ready for it) we can cut Jackrabbit 3.0 as the stable Oak-based repository. That release (and all 3.x versions) should still contain also the older 2.x codebase for full backwards compatibility (except for features deprecated already in 1.x, those we can drop in 3.0).
