[jira] [Commented] (LUCENE-4020) Tests may not be repeatable across
different platforms/ JVMs due to different locale/ timezone being picked.
[ https://issues.apache.org/jira/browse/LUCENE-4020?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13261075#comment-13261075 ]
Dawid Weiss commented on LUCENE-4020:
-------------------------------------
I think the "reproduce with" line should explicitly state the timezone and locale picked for the test. Granted, certain combinations will be invalid on other JVMs/ systems, but at least it's explicit what should be used?

> This is because the source array can be/ is different for each system/ JVM. So this pick is not repeatable for example:
> {code}
> /**
> * Return a random Locale from the available locales on the system.
> */
> public static Locale randomLocale(Random random) {
> Locale locales[] = Locale.getAvailableLocales();
> return locales[random.nextInt(locales.length)];
> }
> {code}
> I don't think there is much we can do to make it repeatable (other than maybe enforcing locale using system property).
