I think you are talking about https://openjdk.org/projects/zero/. That 
was relevant when Zero was an active project. It is since long 
integrated into the mainline JDK, and that project is in effect defunct.

To build a JDK with Zero enabled, run "bash configure 
--with-jvm-variants=zero". If you are interested in implemention 
details, look for files and directories that include "zero" in the name 
in src/hotspot.
