Andre, Even, Jody,
Thank you for your insights.
Based on your advice, it sounds like it will be unwise to try to migrate
all java based OSGeo applications to OpenJDK by our OSGeo-Live5.5
release due in March 2012.
As such, I propose that Sun Java be included on OSGeo-Live5.5.
I'm hopeful that we can find enough space to include OpenJDK, (ideally
version 7) on this and future OSGeo-Live releases, and start moving all
applications across to OpenJDK as soon as they are available. This will
mean that the OSGeo-Live community can be drawn upon to help with
testing which hopefully can be seen as a positive for java projects.
Does this sound reasonable?
Alex, it would be great if you could start the build process so that we
can determine whether we can find sufficient space to include 2 versions
of java on OSGeo-Live.

Questions for Geotools developers:
1. Do geotools based applications work on OpenJDK now?
Not sure; even if they did without a build box configured with OpenJDK
to ensure the library works in that environment it would not be
considered a supported platform for production use. I always figure
"demo" is almost more important then production use as it is a first
impression.
By the same token I would not recommend projects based on GeoTools go
live on OpenJDK without appropriate testing.
Perhaps the Geomajas guys could stand up a build box with OpenJDK?
2. Is it possible to migrate geotools based applications to OpenJDK?
Yes; would required volunteer time; hardware to run a nightly build
with that configuration and so on. I recently lost two weeks to a
build box at my current work site that was incorrectly configured to
use OpenJDK rather than Java 6.
3. Can such migration happen before Feb 2012 (for OSGeo-Live 5.5)?
We can help with testing packaged applications, but are looking for
guidance from projects on where we should be focusing our energy.
I do not think so; we would need hardware in place now.
Our developers are an even split between mac, linux and windows
environments. As I understand it mac OpenJDK is not ready yet (with no
sign of arrival); windows is troubled.
I would wait for OpenJDK Java 7 to be released; and then set up a
build box at that time.

An easy one is to add the extensions into libs/ext and then run uDig
without its "jre" folder so it uses the system default.
Geosolutions (i.e. Simone or Andrea) is the best point of contact
with respect to compatibility with OpenJDK. Personally I was not
going to bother until Java 7 or Java 8.
You could also try talking to Andrea Antonello who at least uses
Linux and may be able to test?
If you want you can also contact me officially as "GeoTools Officer"
and I will take the question to the geotools-devel email list for
you. However I expect I need a more than "Open JDK" (this page for
example does not give me much to work from
http://openjdk.java.net/install/).

Jody and others,
Do you know if anyone has tested the viability of using OpenJDK
with JAI/ImageIO/ImageIO-EXT (with the geotools based applications)?
What would be involved in testing this? Who would know how?

Need to check out how well or poorly OpenJDK does with the JAI /
ImageIO / ImageIO-EXT combo for geotools based apps.
