Possibly, but that decision is above my pay grade.

They are actually repo forests because they each include JDK8 repo
forests, in the
same way that each jdk7/hotspot* repo included a JDK7 repo forest.
there are some jvm features that are co-developed with the JDK libraries.

jdk8/hotspot doesn't exist, but jdk8/jdk8/hotspot does. The latter is
master version of hotspot, just as jdk7/jdk7/hotspot was the JDK7 master
of hotspot. We plan to promote hotspot builds from hsx/hotspot-main through
hsx/hsx22 to jdk8/jdk8/hotspot. hsx/hsx22 will hold the snapshot of
hsx/hotspot-main that we run through PIT testing.

Yes. Erik Trimble tells me he plans to push hs22 to jdk8 at the end of

Yes. jcheck will be run on every push to any hotspot repo, just as always.
