That's truly admirable, but on a little tangent here: how sad is it if you still have to be on Java 8. Sure, there's probably a small few good reasons for an exceeding small amount of users, but all those enterprises that won't go with the times just because their compliance team won't certify an upgrade, I feel for those folks.
This may well be... And I don't mean to argue over it, but it's just so hard to imagine, having been through this myself, and it's never been very hard, given how stable the JVM has generally been. It's not like I'm asking to upgrade from Python 2 to 3.
