Repository? -- How many lines of development?

[joe darcy]

Hello again,

Last call for comments, in summary the proposal is for JDK 10 to have 
three externally visible lines of development:

* master
* hotspot
* sandbox

If there are no objections by Nov. 30, I think we should go ahead with 
this arrangement.

Thanks,

-Joe
