VFSLogFilePatternReceiver not tailing over sftp

[Mihail K]

Hello,
Chainsaw is loading the remote log file but no new events are added unless I
manually restart the receiver. Is the tailing feature implemented for
VFSLogFilePatternReceiver? Here's my setup:
- apache-chainsaw-2.1.0-SNAPSHOT from people.apache.org/~sdeboy/

- commons-vfs-1.1-SNAPSHOT.jar

- receiver config:
<plugin name="TansrvReleaseLogFileReceiver"
class="org.apache.log4j.chainsaw.vfs.VFSLogFilePatternReceiver">
     <param name="fileURL"
value="sftp://****:*****@78.90.xx.xx///var/opt/tansrv/log/tansrv.log"/>
<param name="logFormat" value="TIMESTAMP LEVEL LOGGER MESSAGE"/>
     <param name="tailing" value="true"/>
<param name="autoReconnect" value="true"/>
   </plugin>

Here is VFSLogFilePatternReceiver's chainsaw log output:
