Thanks for the pointer John. Looks like its the NumberFormat class that
is at fault. e.g. -1 returns "1-" when NumberFormat.format() is called.
public class NumberFormatTest {
public static void main(String[] args) {
Locale locale = new Locale("ar", "AE");
NumberFormat format = NumberFormat.getNumberInstance(locale);
String f = format.format(-1);
System.out.println("Format: " + f);
}
}
I will log a bug against the JDK.
