Yes, if the change is reviewed & approved for 7u at the same time it is proposed for 8 as well.

The rationale behind that the process for getting changes into 8 does not seem to be defined yet, afaict from the JDK 8 web page, so non-Oracle developers need a path to get critical fixes into 7u that doesn't require them to conquer the terra incognita of JDK 8 processes first. In those cases, we'd still like the fix to be on its way into 8 - i.e. proposed for inclusion into 8, following whatever public process for accepting changes are/will be in place there.

In addition, as Erik said, there could be scenarios where we need to address an issue in 7u immediately, so allowing that seems like a good idea. There is a 
difference between allowing it and encouraging it, though, so that's why it's a 'special exception'.

I think that 'it depends': for some changes, I'd expect us to want to see the fix go through more 'bake time' in 8 then for others (and to indicate their preference in the approval mail).

> - The langtools group have some cases where a fix is already in JDK 8, and the patch for 7u is the same, and the webrev for the patch is not in a public place.  Would it be ok to just include a link to the JDK 8 changeset in the request for push message, eg:
>       http://hg.openjdk.java.net/jdk8/tl/langtools/rev/0d6d41563040

Yes.

cheers,
