JEP proposed to target JDK 11: 318: Epsilon: An Arbitrarily Low-Overhead Garbage Collector (original) (raw)

My preferences would be:

  1. Use the -XX:+UseNoGC flags, since it more clearly communicates to the users that this is not a fully fledged GC.

  2. Don't use an alias. GC aliases tend to cause problems for the @requires tags in the jtreg tests.

  3. Make -XX:+UseNoGC an experimental flag. I think this feature would be next to useless if it was only available in debug builds.

Thanks, StefanK

If no such objections are raised by 23:00 UTC on Thursday, 18 January, or if they're raised and then satisfactorily answered, then per the JEP 2.0 process proposal [1] I'll target this JEP to JDK 11. - Mark
