And live for 1 year only on latest and 17. Which is putting load for one year to 1/2. But the cost of not having 11 (and 8) will be felt by fedora users more, then having static jdk from repos. > Unluckily, with new future system jdk, we will need to boostrap it by latest, keep it as secondary jdk at least for one , better two, fedora cycles, so again we will be in 3 jdks x 3 systems. > Sure, we do not need to backport newest future system jdk to older fedoras, but usually the users want us to do so. tbh, I do not have strong preference on it. it is like 51 for backport, and 49 for not. Even with knwoledge of TCK burden. Is this based on user requests, or is this only what you *think* users of OpenJDK on Fedora need? Speaking for myself, I have never used anything other than the default "system JDK" for running Java applications on Fedora. What would you think about the following scenario: - Fedora X defaults to new OpenJDK LTS N - Fedora X keeps OpenJDK LTS N-1 so it's possible to revert the change - Fedora X+1 drops OpenJDK N-1, since the newer OpenJDK N was already the default for one release - do not backport OpenJDK n to Fedora X-1 and X-2 - keep java-latest-openjdk, as you seen to need this for bootstrapping new OpenJDK releases You could even drop java-latest-openjdk from all branches but rawhide, since it's only needed for bootstrapping there. This should pretty dramatically reduce the size of your test matrix. Applying the current numbers: - Fedora Rawhide: java-17-openjdk (default), java-latest-openjdk - Fedora 36: java-17-openjdk (default), java-11-openjdk (in case the default needs to be switched back), java-latest-openjdk - Fedora 35: java-11-openjdk, java-latest-openjdk > With much more stress about possible integration issues and with - imo(!) - considerable negative imapct to fedora. Would this reduced set of supported OpenJDK versions, but keeping the "latest" version, address this "considerable negative impact"?
