I don't think that this change would require any packages to be ported to Java 11. Definitely not all of the packages that currently don't work with Java 11. Thanks to "Decouple system java setting from java command setting" change [1] applications in the distribution use specific OpenJDK version on which they were tested, not system Java. Even if Fedora defaults for /usr/bin/java etc. are changed to Java 11 then applications (that are conformant to packaging guidelines) will continue to be ran on OpenJDK 8 unless they are configured to be ran with a specific OpenJDK version. It would be nice to have at least a draft schedule for retirement of OpenJDK 8 so that maintainers can test their packages with more recent Java versions and port their packages if necessary. Fixing *all* packages should not be needed - in cases where maintainers are absent or don't have time to do that, their packages should be retired and not block the whole distribution from moving forward.
