Hi,
I'm no elisp nor java expert but it seems to me the workflow you describe
has already been implemented by Aemon Cannon with his
https://github.com/aemoncannon/ensime . His emacs mode is specific to
Scala, but to my understanding the protocol of communication between emacs
and the jvm process isn't (based on slime, I think). Anyway, there maybe
some ideas or even code to grasp out there...?
