Feedback on Shenandoah GC on b118 private build

[Christine Flood]

>> 4.- Having said all this, I have to say that I'm really impressed with the low pauses I've observed with the Shenandoah GC.
>> I was expected to see lower throughput in my Application than with G1 or much higher memory usage due to the forwarding pointer added to all objects (and the fact that pointers are not compressed for heaps below 32 GB).
>> However, what I've observed is similar throughput and CPU usage (except during the cycles that CPU spikes to 100%), and memory usage is only around 10% higher (or even less) on static objects

Shenandoah does work with compressed oops.
