Per the JDK 13 schedule , we are now in the Release Candidate phase. The stabilization repository, jdk/jdk13, is open for P1 bug fixes per the JDK Release Process (JEP 3) . All changes require approval via the Fix-Request Process . If you’re responsible for any of the bugs on the RC candidate-bug list  then please see JEP 3 for guidance on how to handle them. We’ll tag the first Release Candidate build shortly. - Mark  https://openjdk.java.net/projects/jdk/13/#Schedule  https://openjdk.java.net/jeps/3  https://openjdk.java.net/jeps/3#Fix-Request-Process  https://j.mp/jdk-rc
