Research direction

Start with src/main/resources/oceanbase-table-client/log/log4j/log-conf.xml and reproduce the failure with log4j 1.x enabled. Trace the missing com.alibaba.common.logging.spi.log4j.DailyRollingFileAppender reference and verify that logging initializes without a ClassNotFoundException.
