I'm working on the changeset for that. I need to make sure all the 
langtools tests pass before getting it out for review.

At the start of JDK 9, I filed a number of bugs against JDK 10 and 
tagged them "jdk10-b01" but it is not an exhaustive list. I've started 
filing and tagging bug for "jdk11-b01".

Certainly at some point.  A good number of refactorings need to wait 
until the boot JDK is upgraded. On the other hand, there is an argument 
for JDK 9 being a bit further along before using it for bootstrapping.

Some pieces of the infrastructure will likely need some updates...
