Please do not 'reply all', send concerns or issues to just the build-dev or build-infra-dev aliases. The very latest README-builds.html file is: http://hg.openjdk.java.net/jdk8/jdk8/raw-file/tip/README-builds.html This documents the new build makefiles only. As with all documents of this type, it will always be a work in progress. -kto
