Description

The script and extensions are not currently parsed. Seems like they were added in 1.7 only too so it'll probably require Java-version-specific workarounds.

  public void testLocaleRoundTrip() {
    for (Locale locale : Locale.getAvailableLocales()) {
      String s = locale.toString();
      try {
        Locale back = LuceneTestCase.localeForName(s);
        assertEquals(locale, back);
      } catch (Exception e) {
        System.err.println("Failed roundtrip: " + s + " (" + e.toString() + ")");
      } catch (AssertionError e) {
        System.err.println("Not equals: " + s + " (" + e.toString() + ")");
      }
    }
  }

Example locales that don't pass.

th_TH_TH_#u-nu-thai
ja_JP_JP_#u-ca-japanese

Interestingly, some that do pass the reverse trip are not .equal to their originals:

Not equals: sr_ME_#Latn (java.lang.AssertionError: expected: java.util.Locale<sr_ME_#Latn> but was: java.util.Locale<sr_ME_#Latn>)
Not equals: sr_BA_#Latn (java.lang.AssertionError: expected: java.util.Locale<sr_BA_#Latn> but was: java.util.Locale<sr_BA_#Latn>)
Not equals: sr__#Latn (java.lang.AssertionError: expected: java.util.Locale<sr__#Latn> but was: java.util.Locale<sr__#Latn>)
Not equals: sr_RS_#Latn (java.lang.AssertionError: expected: java.util.Locale<sr_RS_#Latn> but was: java.util.Locale<sr_RS_#Latn>)
