I don't see a change to the actual JDK version as part of this ?? hat's 
the change that will cause hotspot to fail to build in debug mode as 
soon as the version is bumped - I filed:

https://bugs.openjdk.java.net/browse/JDK-8193364

to at least get over that.

Okay. It's very hard to discern what uses of "RELEASE_11" pertain to 
"-release" support and what just pertain to -source/-target. ??

test/langtools/tools/javac/versions/Versions.java looks like it needed 
some updates for JDK 10!
