Локализованные данные/время встроенного образа GraalVM ⇐ JAVA

[Anonymous]

В этом примере:

Код: Выделить всё

final var ARABIC_GREGORIAN_DATE_FORMATTER = DateTimeFormatter.ofPattern("EEEE dd\\MM\\yyyy G").localizedBy(Locale.forLanguageTag("ar"));
final var ENGLISH_GREGORIAN_DATE_FORMATTER = DateTimeFormatter.ofPattern("EEEE dd/MM/yyyy G").localizedBy(Locale.ENGLISH);

var now = Instant.now();
String arabicGregorianDate = ARABIC_GREGORIAN_DATE_FORMATTER.format(now.atZone(ZoneId.systemDefault()));
String englishGregorianDate = ENGLISH_GREGORIAN_DATE_FORMATTER.format(now.atZone(ZoneId.systemDefault()));

Log.info("arabicGregorianDate = " + arabicGregorianDate);
Log.info("englishGregorianDate = " + englishGregorianDate);

При работе в режиме JVM я получаю следующий результат:

Код: Выделить всё

arabicGregorianDate = السبت 18\10\2025 م
englishGregorianDate = Saturday 18/10/2025 AD

Однако, когда я компилирую его в собственный образ GraalVM и запускаю, я получаю следующий результат:

Код: Выделить всё

arabicGregorianDate = Sat 18\10\2025 CE
englishGregorianDate = Saturday 18/10/2025 AD

Обратите внимание, что арабское слово, обозначающее субботу, السبت заменено на Sat, а م — на CE?
Я предполагаю, что некоторые данные (CLDR?) отсутствуют в собственном изображении и для включения этих данных необходимы некоторые настройки. Как это сделать? Попробовал агент трассировки GraalVM, но это не решило проблему.
Я также использую -H:IncludeLocales=ar,en.

Изменить:
Я нашел необходимые ресурсы локализации внутри модуля jdk.localedata, в частности, в sun.text.resources.cldr.ext.FormatData_ar.
Однако я пытался добавить их в достижимость-metadata.json, но это не сработало.

Изменить 2:
Я добавил параметр -H:+TraceLocalizationFeature и заметил, что пакет ресурсов sun.text.resources.cldr.FormatData с языковым стандартом ar включен в собственный образ (но не работает):

Не знаю, почему FormatData указан дважды для каждой локали. Также не уверен, что такое условие ConfigurationCondition(type=class java.lang.Object, runtimeChecked=true).
