Hi. In your latest jdk15 versions, we found something not quite right. a related pr is at https://github.com/apache/commons-lang/pull/558 In short, some codes like this cannot pass tests for some Locale like "ff_LR_#Adlm"
* @Test public void java15BuggyLocaleTest() throws ParseException { final String buggyLocaleName = "ff_LR_#Adlm"; Locale buggyLocale = null; for (final Locale locale : Locale.getAvailableLocales()) { if (buggyLocaleName.equals(locale.toString())) { buggyLocale = locale; break; } } if (buggyLocale == null) { return; } final Calendar cal = Calendar.getInstance(GMT); cal.clear(); cal.set(2003, Calendar.FEBRUARY, 10); final SimpleDateFormat sdf = new SimpleDateFormat(LONG_FORMAT, buggyLocale); final String formattedDate = sdf.format(cal.getTime()); sdf.parse(formattedDate); sdf.parse(formattedDate.toUpperCase(buggyLocale)); sdf.parse(formattedDate.toLowerCase(buggyLocale)); }* BUT in jdk 8-14's all locales can pass the tests, only ones newlly added in jdk15 fails. I wanna know whether it be by design or just a bug.
