RFR: JDK-8200083: Bump bootjdk used for JDK 11 at Oracle to JDK 10

[Jonathan Gibbons]

Erik,

Why bother?  What are you trying to achieve?

Either the boot JDK is JDK 9, or it is JDK 10.  This should be a clear 
decision.

If internally at Oracle, we use 10, then as soon as code creeps in that 
relies on 10 features, we've broken the commitment to the community for 
allowing 9 as a boot JDK.
