yes, and I think there is the wrong conclusion that *OpenJDK* LTS releases will get five years of support. What I am reading is that OpenJDK source releases will be made for 18 months (three updates), not more, and that the sources for those Oracle releases are not made public. > Assuming that Debian will stick to the LTS releases as defined by Oracle > I can see the following consequences: > - openjdk-9 will not be part of Buster, and we should aim for openjdk-11 > instead. > - If the freeze for buster starts in December 2018, we'll barely have 2 > months to complete the transition.
