We have four Shen experts on board, Roman, Aleksey, Kelvin, and William, so believe it's doable before RDP2 in July. In the worst case that we fail, we'd emulate ZGC and move GenShen to it's own directory as an entirely separate collector before RDP2. Make sense?

Unsolicited advice: If you’re planning for this amount of change during RDP 1 then I’d say that you’re not ready for RDP 1.

If this patch were less isolated from the rest of HotSpot then I’d be extremely nervous.
