정확한 원인과 해결책은 모르겠으나,
log4j.appender.WEBAPP.layout.ConversionPattern=[%d{ISO8601}][%-5p][%c:%M:%L] %m%n

ConvertionPattern에 %d 부분에 ISO8601을 다음과 같이 수정.

log4j.appender.WEBAPP.layout.ConversionPattern=[%d{yyyy-MM-dd HH:mm:ss}][%-5p][%c:%M:%L] %m%n

원래 {ISO8601} 부분이 없었더라고, {yyyy-MM-dd HH:mm:ss} 부분을 넣어서 해결
