anyframe-sample-services 빌드 오류

Anyframe-eMarketplace-3.0.1-Struts-1.5-src.zip 를 다운로드 받고
anyframe-sample-services의 build.xml을 실행할 경우

iajc가 실행되면서 같은 에러가 발생합니다.

주석 처리된 javac 로 컴파일 하면 아래와 같은 에러가 발생합니다.

----------------------------------------------------------
compile:
[javac] Compiling 51 source files to C:\workspace\anyframe-sample-services\build\classes
[javac] C:\workspace\anyframe-sample-services\src\main\java\net\sf\log4jdbc\DataSourceSpy.java:14: net.sf.log4jdbc.DataSourceSpy is not abstract and does not override abstract method isWrapperFor(java.lang.Class<?>) in java.sql.Wrapper
----------------------------------------------------------

결론적으로 배포된 형태로는 빌드가 안되는 상황인데 확인 바랍니다.
