Subject [jira] [Commented] (LANG-799) DateUtils#parseDate uses default locale; add Locale support
Date Mon, 24 Sep 2012 00:13:08 GMT


Sebb commented on LANG-799:

Java 7 has many more Locales. It so happens that the first different format string for Java
1.7 use formatting entries that are not in the standard pattern.

Removed the test, as it no longer applies (we don't use localized formats)

LANG-799 - DateUtils#parseDate uses default locale; add Locale support
Remove inappropriate test - we don't use localized formats

> Similar issue as
> Following line throws an ParseException on a German system:
> d = DateUtils.parseDate("Wed, 09 Apr 2008 23:55:38 GMT", new String[] {"EEE, dd MMM yyyy
HH:mm:ss zzz"});
> Reason: parseDate internally calls SimpleDateFormat without providing a locale. This
causes "MMM" to be interpreted using the system locale. If the system is German, the date
is trying to be interpreted as German date.
> I see following solutions:
>  A) Always instantiate SimpleDateFormat with Locale.ENGLISH
>  B) Make two instances of SimpleDateFormat. One without providing a locale and one with
Locale.ENGLISH. Try two parsings
>  C) Make as many SimpleDateFormat instances as locales are availble iterate over all
instances at the parsing attempts.
>  D) provide an additional (optional) parameter to parseDate for providing a Locale
> I would prefer B) as this seems the best trade-off between internationalization and local
> What do you think?
