How to customize currency formatting in MessageFormat in ICU4J

[godosrats]

I have a system that generates a lot of documents. Its contents are defined in ResourceBundles. I want to customize the way MessageFormat prints currency values. Sometimes I want it to display currencies without fraction digits (but not always). This should be working as expected but it is not:\[code\]System.err.println( com.ibm.icu.text.MessageFormat.format( "{0,number,\u00A4#}", new com.ibm.icu.util.CurrencyAmount(1, com.ibm.icu.util.Currency.getInstance("USD"))));\[/code\]Unfortunately it prints out:\[code\]US$1,00\[/code\]Does anyone of you use custom formats for currency in resource bundle 'properties' files?I don't want to change it system wide.And by the way this works fine with java.text.MessageFormat.
