This stuff would be merely academic if there were no story for how
old JVMs play with the new features. So for me a big part of the
puzzle of method handles has been to build in a backward-
compatibility story that lets them be emulated on old platforms, with
efficiency no less than (say) your JRuby invokers.
Then it becomes feasible to have the dynlang backend perform a JVM
version check at boot-up, and choose better vs. best implementations.
And I hope a similar compatibility story can be found for the
anonoymous class loader.
Best,
