Flip -XX:+UseShenandoahGC on by default in shenandoah/jdk9?

[Aleksey Shipilev]

It probably can, but you have to conscientiously have it your env, which
forces you have the Shenandoah-specific env, if you also do other
development.

But maybe you're right: there is a circularity problem with builds. The
bug in Shenandoah may break the JDK build (since current JDK 9 builds
part of itself with the interim JDK) -- the very same build you would
like to debug.

Thanks,
