Good. Thanks for the info.

That's strange. There should be no difference in MethodHandle stub
management between 8u & 9 now (once allocated they stay forever). 9 has
segmented code cache feature and it can lead to observable differences
in behavior.
How many iterations does the test perform on 8u & 9? What if you
increase the number? Also, I'd suggest you to monitor code cache usage
during the run and when the test finishes.
Best regards,
Vladimir Ivanov
