Good catch! These don't work with ZGC either. As far as I can tell, 
these tests are not part of any test tier, so they are never executed in 
our CI pipeline and have gone under the radar.

I'll file a bug and add the appropriate @require tag to exclude ZGC. I'm 
not sure if there's a reason they are excluded from our CI, or if they 
should be added. Leonid, do you know?

Thanks!
