Open-Source JPMS / Panama Projects?

[leerho]

Thank you all!

My apologies, what I wrote was a little confusing, allow me to clarify:

I am seriously looking at *redesigning* our JDK8 Library using Java Modules
(sorry, I thought JPMS was the proper term :) ) leveraging JDK16+/FMA and
completely replacing the need for Unsafe, etc.  (Not just adapting our JDK8
code to access Java internals using JVM args.)

Samual & Ty, thanks for your JavaCPP & *BlueGoliath/ctype_h* references.
We also have a C++ part of our library where leveraging something like what
you have done may be useful.

Nonetheless, if there are any other readers out there with references to
open-source references to multi java module implementations (perhaps
implementing parts of Panama), it would be greatly appreciated.

Lee.
