Sure, we will share any benchmark results we have, although we likely
won't have too much time to spend on it in the near term, since we are
busily fixing bugs for JDK 9. As for getting this into JDK 9, it is way
too late for something of this scope. We are already past feature freeze
and are now in bug fix and stabilization mode. Yes, there is a process
where a few small enhancements might be considered , but even those
require JDK 9 release team approval, which is very unlikely for anything
that rises to the level of a new feature.
I hope JDK 10 won't take as long as JDK 9 is taking, but as there isn't
a proposed JDK 10 project yet, we don't know the timeline. I expect we
will know more in the next couple of months.
With strong encapsulation, the only way to access internal
implementation classes is via a command-line switch to add qualified
exports for the internal packages that you access. Note that any such
use of internal packages is fragile and could break at any time, but is
an option for applications that bundle a specific version of the JRE.
