Hi all, This is a heads-up that the implementation of JEP 475 (available at https://github.com/robcasloz/jdk/tree/g1-late-barrier-expansion) now meets its goals for the x64 and aarch64 platforms, and we intend to target it to JDK 24. If this is approved, we will submit the RFR early during the JDK 24 development cycle and expect maintainers to contribute the changes required to migrate the remaining platforms into the JEP changeset. Please have a look at the x64 and aarch64 changes in the current JEP implementation (subject to minor changes) to estimate and plan the work required to migrate each platform.
Thanks, Roberto CastaƱeda Lozano (HotSpot compiler team at Oracle)
