try this:
<plugins>
<plugin>
<groupId>org.mortbay.jetty</groupId>
<artifactId>maven-jetty6-plugin</artifactId>
<configuration>
<scanIntervalSeconds>10</scanIntervalSeconds>
<contextPath>/koma-web</contextPath>
<systemProperties>
<systemProperty>
<name>org.apache.commons.logging.Log</name>
<value>
org.apache.commons.logging.impl.SimpleLog</value>
</systemProperty>
</systemProperties>
</configuration>
</plugin>
</plugins>
I think that the reason for this is explained in the maven-jetty6-plugin page.
