I’m curious to hear about yours and others’ experiences with containerizing Java applications in such environments. I used to work in a place that traditionally had such restrictions on JDK versions, but after the internal IT environment moved towards running applications within containers, either on Kubernetes or on public cloud platforms’ container runtimes, that restriction became unnecessary since the application would be shipped to production alongside its compatible JDK.

While there were still restrictions on exactly what JDK you could run for other reasons, such as security/stability, common developer experience, etc, it at least allowed teams to immediately adopt the newest LTS release (17 at the time I left) with little restriction.
