Shenandoah GC

[Pas]

Hello,

Check these:

It'll be avialable in RedHat's JDK builds: Shenandoah is shipping in Fedora
starting with Fedora 24 and as a tech preview in Rhel 7.4. Running standard
OpenJDK testing with -XX:+UseShenandoahGC should be sufficient. (You can
see that it's included in the changelog:
https://koji.fedoraproject.org/koji/buildinfo?buildID=1008667 )

I'm not affiliated with RedHat, nor with Oracle, and haven't tested it, but
planning to evaluate it next year on a new project. (But I'd need an
Ubuntu/Debian based build anyhow.)

Regards,
Pas
