        BaseFory fory = Fory.builder()
                .withLanguage(Language.XLANG)
                .requireClassRegistration(true)
                // replace `build` with `buildThreadSafeFory` for Thread-Safe Usage
                .build();
        fory.ensureSerializersCompiled();
    }
}

We have not support graalvm for Fory xlang mode, the error is expected. Maybe we can add xlang support in next version.
