 "INFO" 등과 같이 여전히 영어로 표시됩니다.

이번에는 동일하게 설정 후 Tomca 8.0.38을 기동해 보겠습니다.

 "정보"라고 한글로 나옵니다! 어떻게 된걸까요.

org.apache.juli.OneLineFormatter 클래스 확인해 보겠습니다.

먼저 8.0.37입니다.

    101         // Severity
    102         sb.append(' ');
    103         sb.append(record.getLevel());

이번에는 8.0.38입니다.

    101         // Severity
    102         sb.append(' ');
    103         sb.append(record.getLevel().getLocalizedName());
