Hudson: HTTP listener already in use error

I'm trying to setup Hudson on a Windows server.

When I attempt to run Hudson with the command java -jar hudson.war, then I receive an error that the address is already in use for the HTTP listener.

I've confirmed that port 8080 (the default Hudson HTTP port) is not being used. I have also tried starting Hudson on another port (java -jar hudson.war --httpPort=8888) with the same error.

If I browse to http://localhost:8080, then I get an 'It works!' message on the web page. However, if I browse to http://localhost:8080/hudson, I receive a 404 error.

Here is log:

I downloaded the latest .war file from http://hudson-ci.org/download/war/, specified port 8888 instead of 8080, and now it works. Looks like there must be something running on port 8080 and the version that I had tried to use earlier than 1.381 had an issue.
