Reminder: JDK 10 enters Rampdown Phase One in < 18 hours

By way of reminder, if there are still any fixes that anyone wants to 
get in to FX for JDK 10, you have until tomorrow at 16:00 UTC (8am 
Pacific). Please allow sufficient time for it to be reviewed.

Anything pushed after that time will be for JDK 11 by default. Any 
exceptions will need to follow the Rampdown Phase One process. Details 
are still pending, but basically it will be similar to JDK 9 rampdown. 
We might approve P1-P3 bugs (and not all such bugs will be approved) , 
as well as some (not all) P4 test bugs and doc bugs. Other P4-P5 bugs 
and all RFEs can wait for JDK 11.
