Jigsaw/JDK requirements

[Jonathan Gibbons]

Jigsaw folk,

(Thinking aloud a bit)

Are there any de-facto requirements coming from the desire to  
modularize JDK?
Specifically, is there are constraint to keep the shape of the source  
tree largely
unchanged, or would we entertain the notion of reorganizing the source  
tree
by module?  Would the SCM implications of that be way too onerous?

I ask, because it again comes up in the context of the shape of the  
classes tree,
and the desire to have the classes directory structure be isomorphic  
to the
source directory structure -- and Alex recently re-suggested encoding  
the
module name (but not the version, this time) in the classes/ hierarchy.
