[cp-patches] RFC: Fix for "XXX" use in java.util.Currency

[Andrew John Hughes]

The attached patch allows examples such as the following:

NumberFormat.getCurrencyInstance(Locale.ENGLISH).getCurrency()

to succeed with the result of a Currency instance containing "XXX"
rather than throwing a NullPointerException.  This is Sun's behaviour,
which is made possible by allowing "XXX" to be supplied to
Currency.getInstance(String).  This is something we have discussed
before, which has lead to the introduction of the String version
of this value in java.text.DecimalFormatSymbols (11 Jan - Fix for Bug #11545).

Should we allow this horrible design decision to creep into
GNU Classpath?  Comments please.

Changelog:

2005-03-28  Andrew John Hughes  <address@hidden>

        * java/text/DecimalFormatSymbols.java:
        Added retrieval of "XXX" instance in place of null.
        * java/util/Currency.java,
        (Currency(String)): New constructor for the XXX special case.
        (getInstance(String)): Allow special case of "XXX".
