Only P1-P3 bugs fixes are allowed to push into jdk9 now

[Vladimir Kozlov]

Hi Volker,

The general internal Oracle consensus after discussions was that we may 
allow only very small high priority RFEs for external ports code. It 
should use FC extension process we used before (labels and request 
comments) and approved case by case. And this is for limited time only - 
we all want to have jdk 9 stable on all platforms when it is released as 
Andrew said.

And definitely not if changes touch a common code. If you need then 
split it into separate changes as bug if possible - I assume you can 
have cases when you need to add #ifdef into existing tests, for example.

Also I would like again to enforce priority limit to P1-P3. If you think 
a fix should go into jdk 9 it should have high priority. Otherwise it 
can wait jdk 10.

Regards,
Vladimir
