getting error trying to create log4j2 rollingfileappender

I'm trying to switch from using FileAppender to the RollingFileAppender using log4j2 (happens both with beta3 and beta4 jars).

I have it configured as:

<RollingFile name="RollingFile" fileName="${logdir}/${filename}" 
    filePattern="${logdir}/app-%d{yyyy-MM-dd-hh-mm-ss}_%i.log" >
    <PatternLayout>
        <pattern>%d %p %C{1.} [%t] %m%n</pattern>
    </PatternLayout>
    <Policies>
        <OnStartupTriggeringPolicy/>
    </Policies>
    <DefaultRolloverStrategy max="20"/>
</RollingFile>  
        ...
<loggers>
          <root level="ERROR">
    <appender-ref ref="RollingFile"/>
    <appender-ref ref="STDOUT"/>
</root>
        ...

and in the code, I'm trying to get the logger this way:

Logger logger = LogManager.getLogger(this.getClass());

but I'm getting this exception when I run it:

It looks as if the config file is being read and the appender is trying to get created but not sure what I'm doing wrong.

I've tried cutting and pasting other people's RollingFileAppender configuration w/o any modification but I still get the above error.

Thanks.
