minor comment/question: if it's not an InaccessibleObjectException, wouldn't it throw a case match error which might be confusing? Just wondering if a default catch-all should re-raise the original "re: RuntimeException"

The exception would just propagate, as before, if it's not matched by either case. That's what we want, if something else goes wrong.

should this be inside the try:
pointerFields = field :: pointerFields
it seems like we could still record it even if the setAccessible failed?

No, the point is that we don't want to try to access it below; it's not accessible

…ble in Java 9+ ## What changes were proposed in this pull request? Don't use inaccessible fields in SizeEstimator, which comes up in Java 9+ ## How was this patch tested? Manually ran tests with Java 11; it causes these tests that failed before to pass. This ought to pass on Java 8 as there's effectively no change for Java 8.
