JEP proposed to target JDK 26: 516: Ahead-of-Time Object Caching with Any GC

[Mark Reinhold]

The following JEP is proposed to target JDK 26:

  516: Ahead-of-Time Object Caching with Any GC
       https://openjdk.org/jeps/516

  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.

Feedback on this proposal from JDK Project Committers and Reviewers [1]
is more than welcome, as are reasoned objections.  If no such objections
are raised by 20:00 UTC on Thursday, 6 November, or if they’re raised
and then satisfactorily answered, then per the JEP 2.0 process proposal
[2] I’ll target this JEP to JDK 26.
