Hi, The last changes from jdk9/hs-gc has now been pushed to jdk9/hs. This means that jdk9/hs-gc is now officially closed for all changes. A proper lock will be in place eventually. The push job to bring jdk9/hs into jdk9/hs-rt is running now. Any GC related changes should go into jdk9/hs-rt from now on. Thanks, /Jesper
