Error message when starting eXist client

[Swami Kevala]

Recently I have started getting the following error message when I log in via the Java webstart client. Does anybone know what I can do to fix this?

[root@media-1 exist]# bin/startup.sh

Using locale: en_US.UTF-8

WARN: The following JAR file entries from 'org/exist/start/start.config' aren't available (this may NOT be a problem):
    /opt/exist/tools/ircbot/dist/ircbot.jar
