WebDAV deploy fails with error

I was having problems deploying artifacts using the wagon-webdav plugin. I originally thought it was a client problem with the plugin since no errors were showing up in the Archiva logs until I did a tcpdump and found the exception sent from the Archiva server. I assumed all errors in Archiva would output a stack trace in the logs, but apparently this is not always the case. I've attached the HTTP session information showing the stack trace.
