389 // protection domains and null causes. | |
390 // If the last parameter 'to_utf8_mode' is safe_to_utf8, | |
391 // it means we can safely ignore the encoding scheme of the message string and | |
392 // convert it directly to a java UTF8 string. Otherwise, we need to take the | |
393 // encoding scheme of the string into account. One thing we should do at some | |
394 // point is to push this flag down to class java_lang_String since other | |
395 // classes may need similar functionalities. | |
