Repository? -- How many lines of development?

[joe darcy]

Hello,

An update, after some off-list discussions I agree it is reasonable to 
initially maintain a client forest. However, the client forest may be 
retired later in JDK 10 if the testing situation allows. Therefore, the 
proposed lines of development are now:

* master - jdk10/jdk10
* hotspot - jdk10/hs
* sandbox - jdk10/sandbox
* client - jdk10/client

Cheers,

-Joe
