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.
I agree, it's asking for trouble to have some people using JDK N-2 as
the boot JDK, others using JDK N-1. This is on top of keeping boot cycle
builds working where JDK N rebuilds itself, keeping the jrtfs and jimage
support classes buildable with --release 8, and all the other build
complexities. Using JDK N-1 as the boot JDK for the mainstream ports is
hardly a burden as the required boot JDK is readily available. I could
imagine it might be awkward for some ports that don't cross build but
surely that shouldn't dictate how the mainstream builds.
