Follow up code clean up for JDK-8221582

JDK-8221582 addressed rename of jvm-args option to java-options.
Webrev at http://cr.openjdk.java.net/~herrick/8221582/ indicated that not just public interfaces were affected with the rename. However not all tokens containing "jvm" substring was touched.

It would make sense to at least replace JVMArgs with JavaArgs substring:
