RFR (XS) 8210726: Fix up a few minor nits forgotten by JDK-8210665

[JC Beyler]

Hi all,

When doing the work for JDK-8210665, I got confused with the webrevs and
forgot to add Serguei's nits for the patch. I apologize for that and here
they are in a separate bug.

Could I get a review for it?

Webrev: http://cr.openjdk.java.net/~jcbeyler/8210726/webrev.00/
Bug: https://bugs.openjdk.java.net/browse/JDK-8210726

Thanks and sorry again,
Jc
