Subject [jira] Created: (JCR-2515) ISO8601 uses default DecimalFormat constructor using locale specific digits

ISO8601 uses default DecimalFormat constructor using locale specific digits

                 Key: JCR-2515
                 URL: https://issues.apache.org/jira/browse/JCR-2515
             Project: Jackrabbit Content Repository
          Issue Type: Bug
          Components: jackrabbit-jcr-commons
    Affects Versions: 2.0.0
            Reporter: Rob Owen

ISO8601.java uses the default DecimalFormat constructor which uses locale specific DecimalFormatSymbols.
Runnning Jackrabbit in an Indian locale the format() produces a date using DEVANAGARI numeric
digits. The saved version (UTF-8) encoded is much longer than usual and is not transportable.
On parsing, DecimalFormat works, but TimeZone.getTimeZone("GMT+09:30") (with Indian numeric
digits) fails and null is returned from ISO8601. Later this traceback occurs.

ISO8601 probably meant the chars to be ASCII, and so the constructor with a fixed locale is
more appropriate (and this doesn't encounter the TimeZone issue either).

    private static final DecimalFormat XX_FORMAT = new DecimalFormat("00", new DecimalFormatSymbols(Locale.US));
    private static final DecimalFormat XXX_FORMAT = new DecimalFormat("000", new DecimalFormatSymbols(Locale.US));
    private static final DecimalFormat XXXX_FORMAT = new DecimalFormat("0000", new DecimalFormatSymbols(Locale.US));
