Oracle JDBC Driverを使用した場合、QUERYアノテーションにBEGINコメントを記述すると下記の例外が発生する。
※HSQLDB JDBC Driverを使用した場合、正常終了する(例外は発生しない)。

例：org.seasar.dao.impl.DaoMetaDataImplTest#testStartsWithBeginComment 実行時。

org.seasar.framework.exception.SQLRuntimeException: [ESSR0071]SQLで例外(ErrorCode=933, SQLState=42000)が発生しました。理由はorg.seasar.framework.exception.SSQLException: [ESSR0072]SQLで例外(SQL=[SELECT EMP.empno, EMP.ename, EMP.job, EMP.mgr, EMP.hiredate, EMP.sal, EMP.comm, EMP.deptno, EMP.tstamp, department.deptno AS deptno_0, department.dname AS dname_0, department.loc AS loc_0, department.versionno AS versionno_0 FROM EMP, DEPT department WHERE EMP.deptno = department.deptno(+) WHERE ename = ? ], ErrorCode=933, SQLState=42000)が発生しました
