>   Summary: Enhance the ahead-of-time cache, which enables the HotSpot
>   Java Virtual Machine to improve startup and warmup time, so that it can
>   be used with any garbage collector, including the low-latency Z Garbage
>   Collector (ZGC).  Achieve this by making it possible to load cached
>   Java objects sequentially into memory from a neutral, GC-agnostic
>   format, rather than map them directly into memory in a GC-specific
>   format.

Hearing no objections, I’ve targeted this JEP to JDK 26.
