Replace this section:

with:

<!--  all requests from com.test.me.my.Test or descendents go to A2  
and do not propagate to root  -->
<logger name="com.test.me.my.Test" additivity="false">
     <appender-ref ref="A2"/>
</logger>

<!--  any requests except those from com.test.me go to A1  -->
<root>
    <level value="debug"/>
    <appender-ref ref="A1"/>
</root>

</log4j:configuration>


Your configuration would have routed messages from "com.test.me" to  
A1 twice and once to "A2".  Messages from "com.test.me.my.Test" would  
have gone to "A1" twice and "A2" twice.
