backport JEP 344-Abortable Mixed Collections for G1 to jdk11u

[charlie hunt]

Hi Lin,

Since you mentioned long Mixed GCs, have you tried tuning 
-XX:G1MixedGCCountTarget or -XX:G1HeapWastePercent?

I can further explain these two tuneables and when they are useful to 
tweak if you are interested in trying it in the interim.

thanks,

Charlie
