Introduction
The Quality Group are is promoting the testing of Free Open Source Software (FOSS) projects with OpenJDK builds, whether their own, or from someone else. We want to acknowledge projects who are actively testing, providing feedback and list any issues they have found during their testing. This is a great way to improve the quality of the various releases, adding new projects to the list is highly desirable.
How to join the Quality Outreach Program
If you would like to have your Project added to the list below, please below please send an email to quality-discuss or adoption-discuss mailing lists. mailing lists including:
- Project name
- Project Contact
- Actively Tested on: JDK version
- Previously tested on and actively using features from JDK version
If you haven’t already subscribed to these lists then please do so first, otherwise your message will be discarded as spam.
Status indicators
- Indicates we have active testing, feedback & bug reporting on some or all JDKs around the timeframe of the related release - doesn't necessarily mean that the related release is already supported
- Indicates we have intermittent communication on some or all JDKs - doesn't necessarily mean that the related release is already supported
- Indicates will start testing in the near future
