  thanks a lot for the logs. As you may have noticed I closed JDK-
8166500 as duplicate of the existing JDK-8159697 issue. They are the
same after all.
We will continue working on improving out-of-box experience of G1. :)

As hypothesized in the text for JDK-8166500, the 8u and 9-without-aihop 
show the same general issue. The suggested tunings should improve mixed
gc times for now.

Thanks,
  Thomas
