Hi Phil,

I realise it may not be exactly what you are after, but have you 
checked-out Java 9 and the Jigsaw module system?

You will eventually have to make your software Java 9 & Jigsaw 
compatible anyway so maybe it could be a good place to start.

Early releases of Java 9 with Jigsaw have been available for some time.

Also, I am not even sure that JARs are really the way Java is heading 
(especially with Jigsaw).

Just some things to consider...
