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));
