Porting changes between JDK 9 and JDK 8u

[Chris Hegarty]

Hi 8u Maintainers,

Now that the JEP 201: Modular Source Code [1] changes have been integrated into the JDK 9 mainline, porting changes between JDK 9 and JDK 8u will be a little more difficult. To help with this, a porting script [2] has been developed, and checked into the JDK 9 mainline, along with the source code re-organization.

I would like to propose a small change to the process for requesting ports of JDK 9 changes into JDK 8u. It may be a simple change to the Push Approval Request Template [3], or the something more elaborate in the Ground Rules [4], I'm not exactly sure. Essentially, where you typically see a backport approval request with ‘the patch applied cleanly’, you may accept ‘the unshuffled patch applied cleanly’. Where the 'unshuffled patch' is a patch that has been run through the porting script [2].

-Chris.
