* I assume that the diffs other than those of the Cbrt class itself are artifacts of webrev creation and no other (significant) changes are present elsewhere in the patch.
* Based on code inspection, the cbrt port itself appears to be accurate.
* line 487: “hypot” -> “cbrt”
* line 504: probably need to insert a blank line after this line and possibly remove the blank line at 507.

I also ran these tests against an 8 update release where fdlibm is in C; this helps verify the transliteration port is correct. The small updates to constrain the @build directive in the tests to just the random number library allow the regression tests to be run out-of-the-box against JDK 8 as well as JDK 9.
That all sounds good.
