Should happen, all things been well.

Until then, there are alternate HotSpot repositories you can use to
replace the one in upstream 8u:

IcedTea 3.x HotSpot with 8u242 + the AArch64 port:
https://icedtea.classpath.org/hg/icedtea8-forest/hotspot/

AArch64 port HotSpot with AArch64 port + Shenandoah, currently following
8u252 development:
https://hg.openjdk.java.net/aarch64-port/jdk8u-shenandoah/hotspot/

The first will be my base for a patch to include the port in 8u itself.

Thanks,
