Hi David, indeed the hermetic project was proposed under Project Leyden umbrella. The makefile changes are related to the static linking only, e.g.:

- make the existing static build support more complete for demonstrating static linking capability
- produce a needed libjvm.a 
- producing a testable statically linked launcher binary

That gives us a base for exposing/resolving needed runtime work for supporting static linking fully in JDK. Either covering the makefile work by a JEP or handling it as an incremental change without JEP sounds good. The later might fit the current purpose better.
