log4j (%F:%L) (%C:%M) 设定的问题

Question

log4j设置：
<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">

<appender name="STDOUT" class="org.apache.log4j.ConsoleAppender">
    <layout class="org.apache.log4j.PatternLayout">
        <!-- <param name="ConversionPattern" value="%d %p - %m%n" /> -->
        <param name="ConversionPattern" value="%d{ISO8601} %5p [%t] (%F:%L) (%C:%M) - %m%n" />
    </layout>
</appender>

<!-- Set class org.apache.log4j.RollingFileAppender -->
<appender name="FILE" class="org.apache.log4j.RollingFileAppender">
    <!-- Set location of log file -->
    <param name="File" value="./logs/ritem.log" />
    <param name="MaxFileSize" value="10MB" />
    <param name="MaxBackupIndex" value="7" />
    <param name="Encoding" value="UTF-8" />
    <layout class="org.apache.log4j.PatternLayout">
        <!-- <param name="ConversionPattern" value="%d %p - %m%n" /> -->
        <param name="ConversionPattern" value="%d{ISO8601} %5p [%t] (%F:%L) (%C:%M) - %m%n" />
    </layout>
</appender>

<appender name="app_log" class="org.apache.log4j.AsyncAppender">
    <appender-ref ref="FILE" />
</appender>

<root>
    <priority value ="INFO"/>
    <appender-ref ref="app_log" />
    <appender-ref ref="STDOUT" />
</root>

/log4j:configuration

test类：
public class zhouhl {

private static final Logger logger = Logger.getLogger(zhouhl.class);

/**
 * @param args
 */
public static void main(String[] args) {
    for(int i=0; i<1000; i++){
        logger.info("aaaaaaaaaaaaa   " + i);
    }

}

}

日志文件部分输出结果：
