> Following the [JDK-8255796](https://bugs.openjdk.java.net/browse/JDK-8255796) > improvement that ditched the inline contiguous alloc use from Zero, we can > now rely on GC interface to hook the GCs properly. G1 and Shenandoah are a > bit special here, because they require special `Reference.get` handling. > > Note that it does not change the default GC for Zero, because Zero is > implicitly `NeverActAsServerMachine`, which still selects Serial GC by > default. After this change, Zero users can opt-in to G1 or Shenandoah. > > Additional testing: > - [x] Linux x86_64 Zero fastdebug `hotspot_gc_shenandoah` (some lingering > failures about non-enabled compressed oops) > - [ ] Linux x86_64 Zero fastdebug `tier1` with `-XX:+UseG1GC`
