NPE error while undeploying

I just undeployed a webapp I am developing and saw this error in the catalina.log file:

The webapp appears to have been undeployed successfully, but I'm a bit worried about this error message. I've been having some symptoms that I suspect might indicate a memory leak or some failure to free a resource, and I'm wondering whether this error message might be related.

Does anyone have any ideas about what this might mean and/or how to investigate it further?

This happened while running Tomcat 5.5.26, JVM 1.5.0_15, and Windows XP.
