Log4j2.3 rotating log file number incorrectly

We are using Log4j2.3 version for logging and using xml configuration. Here it is like - 

<?xml version="1.0" encoding="UTF-8"?>
<Configuration>
    <Appenders>
        <RollingFile name="testingAppender" fileName="Test.log"
            filePattern="logs/Test.log.%i">
            <PatternLayout>
                <pattern>[%-5p] %d{dd MMM yyyy HH:mm:ss} - %m %n</pattern>
            </PatternLayout>
            <Policies>
                <SizeBasedTriggeringPolicy size="5 MB" />
            </Policies>
            <DefaultRolloverStrategy max="10" />
        </RollingFile>
    </Appenders>
    <Loggers>
        <Logger name="testingLogger" level="debug">
            <AppenderRef  ref="testingAppender" level="debug" />
        </Logger>
    </Loggers>
</Configuration>

Log files are rotating fine. But the LATEST log file is having highest rolling number Example - Test.log7, where it should be Test.log0. Log file numbers are rotating in reverse order.

Need help in this.

This is not incorrect but the default behavior. To get your intended behavior, try setting fileIndex attribute min.

<DefaultRolloverStrategy max="10" fileIndex="min" />
