To my knowledge there has been no effort to support OpenJDK, it's not used
in production in any serious place I know of and
last time I checked graphics performance was very poor, not to mention
resulting in poorer quality maps.
Again afaik, none of the developers is using it, nor the build server is
testing it.

Also please consider that both Geotools and GeoServer are likely to stay on
JDK 6 for quite some time (JDK 6 EOL is
June 2012, my guess is that we'll stay on it for another 6-12 months past
that), so any
improvement in OpenJDK 7 won't help us much.

Given that business requirements are still squarely on Oracle JDK we'd need
some OpenJDK "champion" that takes care of
supporting that enviroment, finds all the changes necessary to make the
apps work reliably on it, and pushes to get the
same in the code base. If someone shows up that wants to carry on the task
I'll be happy to help with a portion of my
weekend spare time hours.
Another option is that the PSC of both projects votes to start supporting
OpenJDK, dedicating the effort to get there and
the continous effort to keep it there (who wants to try the build on both
JDK 6 and OpenJDK before committing?... hmmm)

Cheers
Andrea
