Some questions regardind project Jigsaw

[Luis Santos]

I'm sorry posting here these questions. I tried to read everything i can but
found no definitive responses to my doubts. I'm doing a cientific study
based on modularity in java language and i stoped at JSR294/Jigsaw doubts.
This is an academic study and when i selected this study about 8 months ago,
i tought direction would be Jigsaw project to be incorporated in JDK7. My
intention is to try to demonstrate necessity of having a modular system
implemented in java language. My doubts are based on that my initial tittle
was regardind modularity proposed by jigsaw project. For what i have read
recently, Jigsaw is only a reference implementation (i don't know if this is
true) of JSR204 and the "true" modular specification actually being accepted
is JSt204. IS this the correct interpretation? How does Jigsaw project
relaets to Modules Project? Thank you very much for yout attention.
