  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.
