Dawid Weiss created LUCENE-4021:
-----------------------------------
Summary: Locale representations don't round trip from
toString->new Locale.
Key: LUCENE-4021
URL: https://issues.apache.org/jira/browse/LUCENE-4021
Project: Lucene - Java
Issue Type: Bug
Reporter: Dawid Weiss
Priority: Minor
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.
{noformat}
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.
{noformat}
th_TH_TH_#u-nu-thai
ja_JP_JP_#u-ca-japanese
{noformat}
Interestingly, some that do pass the reverse trip are not .equal to their
originals:
{noformat}
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>)
