     [java] java.text.ParseException: Unparseable number: "-100.00"
     [java] at java.text.NumberFormat.parse(NumberFormat.java:385) ~[?:1.8.0_392]

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Locale locale = new Locale("ar", "AE");
NumberFormat format = NumberFormat.getInstance(locale);
System.out.println(format.parse("-100.00"));

ACTUAL -

Locale locale = new Locale("ar", "AE");
NumberFormat format = NumberFormat.getInstance(locale);

Catch exception and use Double.parseDouble to parse the value when locale is "ar_AE"

FREQUENCY : always
