Maybe in the open source world? In some closed source company codebases that are known to me, there were still million lines of code on JDK8, since efforts to port everything to a newer JDK don't necessarily enjoy a high priority. As an application developer in such an environment one then might even not have the possibiltiy to pick the JDK version of their choice on their own, since as you mentioned there might be dependencies which haven't been updated. In such an environment solutions which don't require a JDK upgrade (Lombok, Kotlin, etc) can certainly help developers. If the upgrade is feasible, I would definitely use the new builtin language features.

> Maybe in the open source world? Here's a report from New Relic about Java use among their customers (who write closed source) from a year ago, and the Java 8 exodus is continuing: https://newrelic.com/resources/report/2022-state-of-java-ecosystem https://newrelic.com/resources/report/2022-state-of-java-eco.... Java 8 is still definitely used in applications that no longer see much development, and it will be some time for before it mostly disappears, but those applications don't benefit from new libraries either.
