Currency Symbols

Had an issue recently where some unit tests that were working on Windows didn't work on OSX. This snippet sums up why:

public void testCurrencySymbol() {
  Locale locale = new Locale("en", "GB");
  String formattedPrice = Currency.getInstance("EUR").getSymbol(locale) + "10.00";
  String badFormattedPrice = Currency.getInstance("EUR").getSymbol() + "10.00";
  assertEquals(formattedPrice, badFormattedPrice); // fails on OSX!
}

Seems a bit weird, but it's sort of logical - you have to pass in your target locale when you get the currency symbol for some other locale.
