이것은 다음과 같은 내용이다.
log4j 1.2.x버전과 1.3.x버전을 쓰실 때
현재 배포된 commons-logging-1.1.jar파일과 문제를 일으켜
웹 컨테이너 리로딩시 불필요한 Exception이 발생합니다.
Apahce site에서 확인 한 결과
[1.0.4 Release - 16 Jun 2004]
"The 1.0.4 release of commons-logging is a service release containing support for both the 1.2.x and 1.3.x series of Log4J releases. "
log4j 1.2.x와 1.3.x를 commons-logging-1.0.4에서 지원합니다.
원래는 1.0.4 이상에서도 지원 한다고 되어 있는데
commons-logging-1.1과 commons-logging-1.1.1에서는 위와 같은 문제가 발생하고 있습니다.
