The implementation CR also already contains some more information about the implemetation (https://bugs.openjdk.org/browse/JDK-8342382), which will also be updated a little before asking for reviews.
we in the Oracle gc team decided that due to the size of the change (+3k, -4.4k LOC) are not waiting any longer for the JEP moving to candidate before asking for reviews.
There is a PR out for review for this change now [4]. I would like to ask you maintainers to have a look/test.
M. Doerr from SAP already confirmed that the change is still working :)(thanks!).
I am not expecting any or any serious issues for the other platforms since not much changed since asking for the ports. However in particular I hope for feedback from maintainers for the ARM (32 bit) and the RISCV port, as I have only been able to perform very limited testing using cross-compilers and emulators there.
Another confirmation for the S390 port that things still work would be appreciated too. :)
Thanks, Thomas [4] https://github.com/openjdk/jdk/pull/23739
