If you are making any changes to the Makefiles or build process in jdk8, please let us know in the build group build-dev@openjdk.java.net. We will need to review and approve ALL Makefile and build changes from now until we change over to the new build-infra Makefiles. The build-infra team can help you determine the equivalent change needed in the new build-infra Makefiles.
