This patch updates the number handling to accept "," and "." for decimal separators. This is a change in behavior from what is described in the Javadoc.

> The {{createNumber()}} method in the {{TypeHandler}} class expects the decimal separator to be a dot ({{'.'}}). However the dot is not used in all the languages as a decimal separator. Most of the European countries, Russia and a lot of others countries uses a comma ({{','}}).
> With the corresponding {{Locale}}, the {{createNumber()}} method fails, throwing an exception.
> For example:
> {code:title=Type.java|borderStyle=solid}
> public class Type {
>     public static void main(final String[] args) {
>         java.util.Locale.setDefault(java.util.Locale.GERMANY);
>         String text = java.text.NumberFormat.getNumberInstance().format(12.34);
>         Number nb = org.apache.commons.cli.TypeHandler.createNumber(text);
>         System.out.println(nb);
>     }
> }
> {code}
