JEP proposed to target JDK 24: 483: Ahead-of-Time Class Loading & Linking

[Mark Reinhold]

The following JEP is proposed to target JDK 24:

  483: Ahead-of-Time Class Loading & Linking
       https://openjdk.org/jeps/483

  Summary: Improve startup time by making the classes of an application
  instantly available, in a loaded and linked state, when the
  HotSpot Java Virtual Machine starts.  Achieve this by monitoring the
  application during one run and storing the loaded and linked forms of
  all classes in a cache for use in subsequent runs.  Lay a foundation
  for future improvements to both startup and warmup time.

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, 14 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 24.
