After its review concluded, JEP 423, Region Pinning for G1, has been Integrated into JDK 22. This JEP proposes to reduce GC latency by implementing region pinning for the G1 garbage collector. This will extend G1 so that arbitrary regions may be pinned during both major and minor collection operations, so that disabling the garbage collection process may be avoided while implementing JNI.
