NullPointerException running Pluto on Tomcat 4.1.27

I've installed Pluto on Tomcat 4.1.27 per the GettingStarted.txt and I
can successfully hit the URL: http://localhost:8080/pluto/portal 

The page is returned with a Test link. When I hit the test link I get
the following NPE on the console while I get a new page with italic
"Test" next to the original Test link. Is this the expected behavior?
Can anyone tell me what this NPE is all about? 

Thanks.
Gus
