Note this is all about OpenJDK and Project Leyden.

There are plenty of other AOT/JIT cache approaches in the Java ecosystem already, with more mature deployment experience of several years, namely:

OpenJ9, Azul, PTC, Aicas, the Android cousin since Android 7

Technology based on process snapshots CRaC for Amazon OpenJDK distro (Correcto), and OpenJ9, is also another approach available for some time.
