[7u communication] Update to JDK 7u ground rules

[Seán Coffey]

Given that we now have JDK 9 forests open and also have the JDK 8 
Updates forests, the JDK 7u ground rules [1] need some slight tweaking 
to describe how a fix should always be fixed first in JDK 9, then 8u and 
then 7u when necessary. Exceptions apply as per usual (rule 1).

I'd like to propose the changes pasted below. If I hear no objections 
before next Wednesday, 16th April - I'll make the update.

regards,
Sean.
