I would note Chris, given your insistence on all this, that your own project Graal is still shipping on Java 8 despite that being many years old. You're now working on moving to Java 11, which is itself already obsolete.

Imagine if tomorrow nobody could download GraalVM anymore because OpenJDK 8 stopped working for some reason (yes I know it's bundled, this is just a metaphor). It could easily be said you had years to upgrade, so why so sluggish? Well, of course, there were actual features you wanted to ship during this time too, not just doing upgrade work, especially given that Java 9 and 10 maybe didn't deliver many compelling upgrades.

Hmmm I take your point, but OpenJDK 8 is maintained.

A better example is the obvious impending transition to ARM, which GraalVM is already preparing for.

Sure, but so is Mojave. It'll be some years before Apple stops shipping security updates to older releases. Until then app vendors saying "don't upgrade macOS" is no different to Java developers saying "don't run this on Java 11 because it doesn't work yet" and we've seen plenty of that.

In fact, I'm guessing the pain of losing Java 8 will be too much for many organisations after so many years of stability and 9/10/11 breaking so much (current Gradle doesn't even work on Java 13!). Maintaining 8 will be a good business for a long time.
