Sounds good. I'll set up a 0.9 milestone in Jira with the immediate
stuff. With that I hope to have an initial 0.9 release ready during

Good point. The main interface is of course the JSR 170 API, that I
think we will be using for the entire 1.x series. I think that a good
roadmap is to target Jackrabbit 2.0 as an implementation of JSR 283.
This may cause a need to make a stable 1.x branch later this year to
allow JSR 283 changes to be more easily introduced. I'm however not
planning to make an immediate branch for 1.x as I think that at least
1.1 should come from the svn trunk.

The other interfaces we need to stabilize are the main extension
points like the PersistenceManager interface for external components
and WorkspaceImpl.createWorkspace() for applications. Would it make
sense to move such interfaces to something like o.a.j.api for clarity
and for flexibility in modifying o.a.j.core?

I've occasionally used japitools (http://www.kaffe.org/~stuart/japi/)
for binary compatibility checking, perhaps we can start using that for
Jackrabbit as well. Does anyone know of a Maven plugin for using
japitools or other similar API checkers?
