All,
A great time was had at JavaOne, including a variety of
Geronimo-related meetings, hacking time in the W and Moscone, a BOF, a
party, etc. Here are some thoughts I put together based on the bits I
was involved with, which I think we'd all like to run by everyone who
couldn't be there.
Also, here are the slides from the Geronimo BOF, that talk a bit about
the various releases:

Thanks,
Aaron
Ebay announced in a BOF that they are deploying their site on
WebSphere CE (Geronimo)!!! Yeah, let's talk about acalability... :)
Vendor Support
- Many vendors are supporting Geronimo, including:
- 24x7 support
- services
- building applications on Geronimo
- building/supporting software stacks including Geronimo
1.1/1.2 Merge
- Major things changed in 1.2: OpenEJB refactoring, JavaMail
providers, initial Maven 2 build script, ActiveMQ 3->4, dynamic EJB
queries
- Still, not that much compared to 1.1
- We plan for the process to be
1) move 1.2 to branches/1.2-pre
2) copy 1.1 to trunk
3) maintain 1.1 in current 1.1 branch
4) merge changes from branches/1.2-pre to trunk
5) eventually whack branches/1.2-pre perhaps
Release Schedule
- 1.0 took too long to arrive (since founding) and 1.1 took too long
to arrive (since 1.0)
- We need to avoid TCK breakage and do a better job of incremental
change
- Some people advocate time-based releases (2/3/4 months)
- Some people would like to see XBean releases more often, outside
the Geronimo release schedule
- Vendors don't like the uncertainty about release dates; most are
still targeting 1.0 because it's here and there's no guarantee when
1.1 will actually arrive
- Overall, there seems to be interest in targeting a 3-month release
schedule for 1.2 (2 months active development and 1 month
stabilization)
- Proposal to target 4 features releases per year with incremental
features available via plugins
Jira Process
- lots of open Jiras
- estimate we have closed 250 for 1.1, and have 500 currently open
- may need to clean up some old/stale issues
- Jira never reflects how close we are to a release
- Many Jiras go unnoticed
- There's not a good way to have a personal work/priority list
separate from the project release/priority list
- Might be good to have 3 Jira "releases": current release, next
release, everything else
- Might be helpful to have someone take responsibility for evaluating
all incoming Jiras for a period of time (1-4 weeks?) and rotate that
responsibility
- Maybe could add custom fiuelds to help us manage it
Java SE 5
- We can develop on Java 5 and support 1.4.2 via Retrotranslator
- It supports most of Java 5, with some caveats regarding
Serialization and new classes added outside of Collections (some
SSL-related stuff, etc.)
- Running on 1.4 with Retrotranslator causes a startup penalty of
~20% (but shouldn't have much effect after startup, when all the
classes are loaded)
- Running on 1.5 speeds startup by 20% and should have benefits after
startup too
- Dain will try a more extensive test and make sure everything works
for us
- Yoko is making good progress. Some holes (e.g. SSL) but we can
probably start integrating and may have this for 1.2 (Rick will work
on this)
Java EE 5
- OpenJPA code is only partially available; more expected soon
- Should be able to implement a JPA factory that lets us give access
to installed JPA implementations
- Should be able to get web features from Jetty 6
- Should be able to get JAX-WS from XFire/Celtix
- Don't have an immediate plan for EJB3 (outside of JPA), though
Spring reportedly has working code we could leverage
- Should be easy to get initial EE 5 features in 1.2, may not have
full support, but this is enough for people to play with
Candidate Features for Future Releases
- Console portlets can be added at runtime
- OpenEJB 2.x revisions

objects, etc.
