The JDK 9 Project has just been created [1][2]. If you contributed at least one changeset to JDK 8 then you will automatically be subscribed to the jdk9-dev mailing list.
If you didn't contribute to JDK 8 you're still welcome to subscribe to the JDK 9 list, but you'll have to do so yourself. Either way you can subscribe, unsubscribe, and adjust your subscription options here: http://mail.openjdk.java.net/mailman/listinfo/jdk9-dev . - Mark [1] http://mail.openjdk.java.net/pipermail/announce/2013-November/000156.html [2] http://openjdk.java.net/projects/jdk9/
