AFAICT, the LocationTech uDig project has not engaged in a Release Review per the Eclipse Development Process
and so cannot issue an official release.
The initial contribution has not been resolved and the IP Team is waiting on a new code drop from the project team.
The downloads include JAI ImageIO 1.1.3. We do have an approved CQ
for JAI ImageIO 1.1 which may partially apply (service releases of approved content do not require review by the IP Team), but I'm pretty sure that there is content in the download that is not included in that approval. Frank, please verify.
Any third party intellectual property that has not been reviewed by the IP Team cannot be included in releases. For completeness, only third party content that has been granted checkin, license_certification, or approval can be included in pre-release (e.g. nightly, integration, or milestone) builds. If these builds include any content that has not received the necessary grants from the IP Team is included in these builds, then that content needs to be removed.
FWIW, it is my understanding that the project was blocked waiting on the Raster Processing Engine project because JAI ImageIO could not be resolved by the IP Team.
Before the project can make a release, the project team must engage in a Release Review. The Release Review cannot start until all of the outstanding intellectual property reviews are resolved.
