How many modules per jar?

[Pisarev, Vitaliy]

I am not sure I hit the right mailing list, kindly redirect me if needed.

I am preparing a lecture for my team about the new module system and wondering whether there is already a set of best practices around this.

For example: should we host each module in a separate jar or should a jar contain more than one module if the list is cohesive enough?

Thanks,
Vitaliy.
