*** 54,69 ****
   * The class is designed so that there's never more than one
   * <code>Currency</code> instance for any given currency. Therefore, there's
   * no public constructor. You obtain a <code>Currency</code> instance using
   * the <code>getInstance</code> methods.
   * <p>
!  * Users can supersede the Java runtime currency data by creating a properties
!  * file named <code>&lt;JAVA_HOME&gt;/lib/currency.properties</code>.  The contents
!  * of the properties file are key/value pairs of the ISO 3166 country codes
!  * and the ISO 4217 currency data respectively.  The value part consists of
!  * three ISO 4217 values of a currency, i.e., an alphabetic code, a numeric
!  * code, and a minor unit.  Those three ISO 4217 values are separated by commas.
   * The lines which start with '#'s are considered comment lines. An optional UTC
   * timestamp may be specified per currency entry if users need to specify a
   * cutover date indicating when the new data comes into effect. The timestamp is
   * appended to the end of the currency properties and uses a comma as a separator.
   * If a UTC datestamp is present and valid, the JRE will only use the new currency
