JDK 13 enters Rampdown Phase One next week, on Thursday, 13 June. Changes intended for JDK 13 should be in the main-line repository (https://hg.openjdk.java.net/jdk/jdk) by 16:00 UTC on that day [1].
At that time we’ll fork jdk/jdk to the JDK 13 stabilization repository, jdk/jdk13, and promote next week’s build (jdk-13+25) and all remaining JDK 13 builds from there.
We'll semi-automatically merge changes pushed to jdk/jdk13 into the main-line jdk/jdk repository, as we have in previous feature-release transitions. This means that:
If you make a change in JDK 13 then you needn't do any extra work to get it into the main line, though if a merge conflict arises then you might be asked to help resolve it.
If you need to make a change in both JDK 13 and the main line then just push it to JDK 13, and wait for the automatic merge to complete.
Changes pushed to jdk/jdk after 16:00 UTC next Thursday will be bound for JDK 14 only, unless they're back-ported.
The jdk/submit repo will continue to be for main-line (jdk/jdk) work. We’ll set up a jdk/submit13 repo for jdk/jdk13 work.
The Rampdown Phase One process is defined in JEP 3 [2].
