Bug: https://bugs.openjdk.java.net/browse/JDK-8153928
Webrev: http://cr.openjdk.java.net/~xiaofeya/8153928/webrev.00/

After changes in JDK-8153737 
<https://bugs.openjdk.java.net/browse/JDK-8153737>, it introduced new 
dependency of java.base/jdk.internal.misc in 
test/lib/share/classes/jdk/test/lib/Utils.java. This leads to two test 
compilation failures.
