I will be at EclipseCon. If you and/or Martin are there, perhaps we can get together to discuss the details there as well.

Thanks for the advice. I have the workspace set up now and the hook is
being activated. Unfortunately, the weaving is not happening. I'll have
to explore a bit more and I'll bring Martin Lippert into the conversation
as well (since he's the original author of Equinox Weaving). After we
learn a bit more, we'll get back to you.

It is a bit more involved to deploy this into your Kepler instance. You
have to be running a Kepler instance with a workspace that has loaded
both the org.eclipse.osgi and org.eclipse.osgi.compatibility.state
projects. Then you have to export the projects using "Export->Plug-in
Development->Deployable plug-ins and fragments" and for the destination
you have to select "Install into host. Repository:". This will deploy
the new framework to your running installation and you must then restart
Eclipse. If all goes well Eclipse will restart successfully on the new
framework.
Note that this is not ready for prime-time, so I suggest you do this on a
Kepler installation that you don't mind blowing up. I find it easier to
just run Eclipse on the new framework by launching a self-hosted Eclipse
instance from your Eclipse workspace while you have the org.eclipse.osgi
and org.eclipse.osgi.compatibility.state projects loaded.

Hi Tom,
Thanks for taking a look at this. AJDT is one of the main consumers
of org.eclipse.equinox.weaving.hook through the
org.eclipse.equinox.weaving.aspectj bundle. It looks like you have
also updated the org.eclipse.equinox.weaving.aspectj bundle. I will
get a chance to try this out next week. Just to be sure, if I check
out this branch of equinox and drop the osgi bundle into Kepler, will
things hang together?
regards,
Andrew
