GWT <replace-with> not working

问题

I am trying to use a custom implementation of LocaleInfoImpl in GWT. For this I created a class CustomLocaleInfo and in my .gwt.xml file like this:

  <replace-with class="my.package.util.CustomLocaleInfo">
      <when-type-is class="com.google.gwt.i18n.client.impl.LocaleInfoImpl" />
  </replace-with>

My class:

public class CustomLocaleInfo extends LocaleInfoImpl {

     @Override
     public NumberConstants getNumberConstants() {

            Notifier.printDebug(">>> getting number constants");

            final NumberConstants nc = super.getNumberConstants();
            return new NumberConstants() {
                @Override
                public String notANumber() {
                    return nc.notANumber();
                }

                @Override
                public String currencyPattern() {
                    return nc.currencyPattern();
                }

                @Override
                public String decimalPattern() {
                    return nc.decimalPattern();
                }

                @Override
                public String decimalSeparator() {
                    return ".";
                }

                @Override
                public String defCurrencyCode() {
                    return nc.defCurrencyCode();
                }

                @Override
                public String exponentialSymbol() {
                    return nc.exponentialSymbol();
                }

                @Override
                public String globalCurrencyPattern() {
                    return nc.globalCurrencyPattern();
                }

                @Override
                public String groupingSeparator() {
                    return ",";//or any custom separator you desire
                }

                @Override
                public String infinity() {
                    return nc.infinity();
                }

                @Override
                public String minusSign() {
                    return nc.minusSign();
                }

                @Override
                public String monetaryGroupingSeparator() {
                    return nc.monetaryGroupingSeparator();
                }

                @Override
                public String monetarySeparator() {
                    return nc.monetarySeparator();
                }

                @Override
                public String percent() {
                    return nc.percent();
                }

                @Override
                public String percentPattern() {
                    return nc.percentPattern();
                }

                @Override
                public String perMill() {
                    return nc.perMill();
                }

                @Override
                public String plusSign() {
                    return nc.plusSign();
                }

                @Override
                public String scientificPattern() {
                    return nc.scientificPattern();
                }

                @Override
                public String simpleCurrencyPattern() {
                    return nc.simpleCurrencyPattern();
                }

                @Override
                public String zeroDigit() {
                    return nc.zeroDigit();
                }
            };
        }

}

Even if I use random names, the compiler does not throw an error.

I am using GWT 2.8.1. Please advise!
