We're reviewing this one on core-libs-dev and the changes involve a small build change to accommodate new locations in src/share/classes/jdk/internal. As it's just pure java code then there is no impact to the new build; for the old build we just need a top-level Makefile, the make/jdk/asm/Makefile is not really needed. The webrev is here:
