Please review this small fix(2 lines changed) for recently added Command 
Line Option Validation tests.

The problem was found in test framework code for double options. 
String.format("%f") was used to format double value and it depends on 
current locale. Thus, on some locales the resulting string with double 
value looks like: 0,999 (with comma) and JVM reports an error when 
trying to parse double command line option with such value. In this fix 
I explicitly add Locale.US to the String.format: 
String.format(Locale.US, "%f", value);

JBS: https://bugs.openjdk.java.net/browse/JDK-8129394
Tested: locally ran with different locale - pass with the fix and fail 
without fix, JPRT.
