This is a point I'm struggling with.
Oracle does not ship 12 with Shenandoah.
At redhat.com there is no link for downloading a Linux JDK with
Shenandoah, only Windows
(https://developers.redhat.com/products/openjdk/download/).
Cannot find it at AdoptOpenJDK.com.
Thanks to you there is https://builds.shipilev.net/, or otherwise I
would need to build it myself (no big deal to build it - I've done it
in the recent past, but I find it so strange that there are no
binaries under a big, easy-to-find, link).
Do you have pointers for a non-RedHat Linux 12-with-Shenandoah binaries?

Will do, thanks!
