Going Java::Current in Production

Java 17 was released in September.

And at Revolut, we immediately knew we wanted 17 quickly!

But JDK upgrades don't just happen overnight.

I'll reflect upon our 8->11 migration: motivation, plan, surprises, and what we found better than before!

We'll discuss tools, alternative JVM languages, and some 3rd party products.

Then I will explain why 17 is so exciting, and what (some) of the caveats and workarounds are.
