After enabling security in Hudson with the following specs:
Security realm: Hudson's own user database
Authorization: Logged-in users can do anything

The IRC bot throws a NullPointerException when I issue "!hudson jobs" through IRC. This behavior started after I set the authorization mode to "Logged-in users can do anything". For Hudson username/password in the configuration I specified my own valid credentials, while I actually don't want the IRC bot to have r/w access, but only to report build status. The error is also reported when I don't specify credentials.

The full error spec:
Jul 23, 2010 2:24:56 PM hudson.plugins.im.bot.AbstractTextSendingCommand executeCommand
WARNING: java.lang.NullPointerException
